4 Recommendations for Installing Self-Drilling Screws

Self Drilling Screws

Self-drilling screws are unique, multi-functional screws. They are designed to drill its own hole into metal and then form threads into the hole. Often used for attachment of steel siding or roofing, they can also be used in other applications where a premade hole is not possible or convenient. While these screws can be a great solution for your application, here are 4 things to keep in mind:

1. Length of Drill Flute

The length of the drill flute must be longer than the thickness of the material being drilled. If the material is too thick, the chips cannot escape, which will cause excessive heat and damage to the screw or mating material. The point length must be long enough to complete the drilling operation before threading starts, otherwise damage may occur.

2. Thread Pitch

For thinner sheet metal applications, a coarse thread (wider thread spacing) is recommended. For thicker metal, (3/8 to 1/2″ thick) a fine thread will work better, creating less drive torque.

3. Thread Length

The thread length of the screw should be sufficient to fully engage into the base metal, keeping in mind that the first few threads are not fully formed. Two to three threads should show on the back side of the base material.

4. Installation Tools

Specialty-corded and cordless tools are available specifically for drill screws which run up to 2500 RPMs for fast setting of screws. Standard drills or drivers may be used as well, but impact drivers are not recommended for hard joint applications that are considered structural. Depth gages are often incorporated into the nose of the tool to disengage the head after it has been properly set. Some tools may also have an adjustable clutch that will allow for proper setting torque.

What You Need to Know About Thread Engagement in Blind Holes

Thread Engagement in Blind Holes

Nuts are designed with a specific proof load strength and thickness that when paired with the proper grade or property class of bolt, the nut will always be stronger. This is good joint design, but what precautions should be taken when designing without nuts and into blind threaded holes?

The main things you need to be concerned with when designing joints with tapped holes are material strength and thread engagement. Generally, you are stuck with a specific material, so the one variable you can change is the depth of thread engagement. Below is a rough guide take from IFI’s “Mechanical Fastening and Joining” handbook by Bengt Blendulf:

Thread Engagement Chart

Tapped Material 8.8/grade 5 10.9/grade 8 12.9/alloy
Steel, hardened 0.8-0.9d 0.9-1.0d 1.0-1.3d
Steel, medium carbon 0.9-1.0d 1.0-1.2d 1.2-1.5d
Steel, low carbon 1.0-1.2d 1.2-1.4d
Cast iron (grey) 1.0-1.2d 1.2-1.4d
Light alloys 1.3-1.6d

What’s the Difference Between Kits and Assemblies?

Kits & Assemblies

The difference between a kit and an assembly is quite simple:

  1. An assembly is taking two or more parts and combining them together to form one ultimate part.
  2. A kit is combining two or more components and either bagging or boxing them together. Typically, this gives the end user the ability to easily assemble the parts without confusion.

Kitting and assembling components is a task that typically involves multiple different items, and can take up a lot of time for both your employees and your company. Every item has its mate and place in different applications and if it isn’t done properly, it can potentially cause a butterfly effect. The result will be failures due to incorrect assembly, loss of production due to having to stop, and having to locate the proper part because it wasn’t kitted correctly.

Kits and assemblies need to be done right. It takes patience, attention to detail, and are extremely time consuming. If you feel you have a kit or assembly opportunity that you need assistance with, please contact Bossard at ProvenProductivity@bossard.com.

How To Improve Your BOM

BOM

What is one of the most asked questions we receive from a new potential customer? “How hard is it for me to get the right fastener in my bins?” There are a lot of things that go into making sure this process runs smoothly.

Good communication about what is needed for a quote is crucial. A good quote process begins with a Bill of Materials (BOM), the Estimated Average Usage (EAU), quality understanding, and an estimated deadline. The BOM should be clean and detailed with dimensions, head styles, drive styles, product types, materials, and finishes.

Every customer has their own way of abbreviating the information to a short description, so paying attention to the details is key. Some fasteners may also be used in a variety of applications. Understanding the business and having a grasp of the BOM will help make sure the right fastener is in the production line. As mentioned earlier, estimated usage, quality requirements, and a reasonable deadline will help with getting the most accurate quote back for review.

What will it take for you to win business, save the company money, and prevent line down situations when switching fastener vendors? Ordering AND receiving the correct parts the first time! Let the experts at Bossard help you review and translate the terminology of a sloppy BOM and get you the correct fastener the first time around.
