A Quick Look at the Koenig Expander Sealing Plug

While the Koenig Expander Sealing Plug is available in an array of materials, they all share one thing in common — exceptional versatility. No matter the substrate, the Koenig Expander works to permanently resist even the most extreme pressures and loads.

  1. Designed for use in base materials of high and low hardness (up to 450 bar pressure), anchorage and expansion of the sleeve in the hole wall in the MB Series is achieved by pressing the ball into the sleeve. 
  2. The CV Series Expander plugs are offered in inch sizes, metric sizes, as well as in different surface treatments and materials. Anchorage and expansion of sleeve in hole wall are also attained by pressing the ball into the sleeve. 
  3. Using the tension/expansion concept, the LK Series is perfect for lower pressure applications (max 60 bar). Once sufficient force is achieved, the expanding element instinctively breaks off at the preset breaking point. 
  4. Suitable for use in high-pressure applications (up to 500 bar) and in light metals, the SK Series also functions based on the tension/expansion concept — where breaking off of the expanding element occurs after achieving sufficient force. 
  5. Suitable for lower pressures, the versatile press-fit and anchoring concept of the LP Series utilizes a conical press-in sleeve. In the installation process, it adapts to the bore while the exterior serration bites into the bore wall.  

The Versatility of the SFC Koenig Expander Tool

Types of Fastener Hardness Testing

Types of Hardness Testing

Hardness defines how a material resists permanent deformations such as indentation. Because measuring this characteristic is a mature technology, several hardness methods are available that produce different hardness values.

Parts like fasteners are typically tested at heat treatment to affect the process and the outcome. However, these tests are also conducted on raw materials for high-strength fasteners or some coating finishes.

Advantages of Hardness Testing

Such tests are quick and easy, relatively inexpensive, and can work on finished components since they do not destroy the specimen, which can be of any size and shape, such as a fastener. In general, mechanical hardness tests rely on an indenter made of tough material, such as hardened steel, carbide, or diamond. It presses into the surface of the test component at a specific force.

The hardness values come from either how deeply the indenter penetrates or the size of the indent with smaller indents signifying harder materials. Higher numbers mean harder materials.

Types of Tests

The following are just three of the major hardness tests. Tables are available for converting one hardness test scale to another. However, some of these values are interpolated because there is no direct mathematical correlation among scales. You should only use conversion tables as a last resort.

Brinell Hardness Test

In the early 20th century, the Brinell Ball Test stood out as the most popular. It presses a hard ball into the test material with a known load. Based on EN ISO 6506-1 standards, a typical value from this test is 600 HBW 1/30/15, which means:

  • 600 – Brinell hardness number
  • HB – Hardness symbol for Brinell
  • W – Indenter type, which is tungsten carbide
  • 1 – Diameter of the ball in millimeters.
  • 30 – kilogram-force (applied force)
  • 15 – Duration of the test force in seconds

Rockwell Hardness Test

The Rockwell Hardness Test starts with a light load and then continues with a heavier load at a specific duration with an indenter. The heavier load is removed, leaving only the indent by the light load. The difference in depth between the two loads represents the Rockwell hardness number. A typical value from this test is 60HRBW, which means:

  • 60 – Rockwell hardness value
  • HR – Hardness symbol for Rockwell
  • B – Rockwell scale symbol
  • W – Ball type, which is S for steel and W for tungsten

Vickers Hardness Test

This test uses a square-based pyramid indenter. (A variant of this test, Micro Vickers testing is reserved for a small or limited area. An example is the carburized surface of a gear for testing the surface, core, and carburized thickness.)

The test impresses as a reference for deciding a dispute between hardness results. A typical value from this test is 640HV30/10, which means:

  • 640 – Vickers hardness value
  • HV – Hardness symbol for Vickers
  • 30 – Kilogram force (applied force)
  • 10 – Duration in seconds

Find Coefficient of Friction (And more!) with Fastener Testing from Bossard

#3 Fastener Testing - r

Whether your products are used in systems that are common or critical, you want to ensure that they meet the high standards of your target market. Bossard can help with 14 state of the art testing labs on three continents that boast ISO/IEC 17025 certification. Our services reward you with high quality at minimal risk.

Our facilities can take charge of the following wide range of fastener tests on your products.

  • Tensile Testing and Compression Strength Testing is a standard procedure that can determine yield point, tensile strength, elongation fracture, and other mechanical characteristics.
  • Hardness Tests / Hardness Profile Measurements rely primarily on measure indentations to test mechanical properties such as case hardness, hardness profile, surface hardness, and core hardness.
  • Friction Coefficient Testing / Torsion Testing can find the coefficient of friction to determine the clamping force and tightening torque. We recommend this test to ensure that screws are tightened in the correct order.
  • Whether at our laboratories or at your location, Torque Analysis uses your original working pieces, which are made of plastic and metals, to determine the tightening torque of your application.
  • Coating Thickness Measurement measures the thickness of the required protective coating by using X-rays and a coating thickness gauge.
  • Spectral Analysis identifies materials and ensures quality control of semi-finished and finished products.
  • Fastening Optimization helps you to choose the right fastener for your application to minimize costs in the supply chain and during production and assembly. We can also deliver the optimum specifications for your fastener.
  • Loosening Analysis examines the bolted joint to determine the right clamping force when subject to different vibrations, forces to transmit, and temperatures of use. It can determine the best way to secure the joint based on the fastener and its function.
  • Corrosion Analysis looks at how corrosion can affect fasteners and other components. We help you choose reliable countermeasures for reducing or removing corrosion from the wide array of corrosion protection systems.
  • Salt Spray Test is a standardized test for evaluating corrosion protection. It determines how different anti-corrosion coatings react on test pieces that are sprayed with a saline solution in the test chamber.
  • Ultra-Sonic Preload Measuring looks at the preloads that are generated when a screw is tightened. Because measuring the preload/clamping force is not easy, we use a special ultra-sonic measuring device that can evaluate how a change in screw length affects preload.
  • Failure Analysis determines the root cause of failures and the best ways to prevent them. Among possible reasons are change of friction conditions, too much or too little tightening, loss of preload due to setting, and corrosion.,
  • Joint Design Calculation, which is based on the MDESIGN tool, enables us to recommend the best design and assembly based on calculations of contact surface pressure, variation of friction, assembly method, and different expansion coefficients of fasteners and other components.

To find out more about how any of our tests can help make quality assurance more reliable and improve the design and assembly of your products, please contact us today at ProvenProductivity@bossard.com.

Body in White Fasteners

Body in White (BIW), which is the main frame of the vehicle that has been joined together using different types of joining processes. The attachment to this structure has many different demands and will usually require high-strength fasteners that are corrosion resistant and are easy to assemble and disassemble. To meet those requirements, we offer the following types of fasteners:

Weld Nuts & Studs

Through welding, metal fasteners such as weld studs, weld pins, and threaded studs and weld nuts are joined to another metal object through an arc at the speed of lightning. The process can be highly automated and depending on the type of welding it can only requires access to one side of the material.

PEM® Large Diameter Clinching

Hardened clinch fasteners increase thread strength and produce clean assemblies. The fasteners can either be installed In-DIE during the forming process or offline using a C-Frame. There are no thermal stresses even with the high resistance to push and torque outs. The resulting clean work environment reduces any concerns about the environment.

Self-Piercing Technology, Flow Drill Screws

These fasteners combine drilling and thread forming to increase the speed of one-sided assembly, which drops to less than one minute. Because the rivets are self-piercing, the material experiences no heat zones during installation. The flow drill screws are highly resistant to vibration and loosening torque.

Structural Blind Rivets

Because they stand out as a strong solution for structural assembly, these fasteners are excellent for high-tensile applications. Only one side is needed for access and one fastener can accommodate up to four rivets with large diameters. The result is an attachment that is both durable and reliable.
