Why Lean Bonding Could Be the Solution You’re Looking For

Lean Bonding

Lean Bonding is an innovative new method of fastening composites and thin metal materials.  Developed by bigHead® Bonding Fasteners, a part of the Bossard Group, Lean Bonding allows users to bond fasteners to composite surfaces with incredible speed and strength, while also providing a solution that does not require drilling holes which can weaken the base composite material.

Lean Bonding allows fasteners to be permanently fixed to a suitable composite surface in as quickly as ten seconds! The process involves use of a bonding fastener equipped with a pre-applied adhesive, activated via rapid induction heating. After applying the fastener to the desired surface, the dry adhesive film rapidly cures, permanently securing the fastener.

Automated, semi-automated or manual installation methods are available, and cause no damage to the base material. Successful Lean Bonding is compatible with fiberglass, reinforced plastics, aluminum, steel and carbon fiber reinforced plastic. It is suitable for use with a variety of adhesives, fastener coatings, and sizes. Additionally, using a pre-applied adhesive ensures uniform adhesive thickness and repeatable bond quality. This makes it the ideal solution for the many technical challenges experienced when assembling composite materials that are not suited for clinching, riveting or welding.

Lean Bonding is a reliable process that offers excellent versatility for high and low production levels and can offer profound improvements in speed, quality, and cost.

Some Facts About Lean Bonding:

  • The fastener has a 24mm head, comes in M5 and M6 sizes, and in 16 or 20mm lengths
  • Wide range of OEM-approved finishes available

How to Avoid Assembly Nightmares – Part 2

Solutions to Assembly Nightmares 2

You are on a deadline. You have two weeks to produce 500 more units to meet your customer’s expectations at a rate of 50 per day so you should be in good shape. Suddenly, you have a problem. Bolts are stretching and breaking on the assembly line. What do you do now?

Your checklist should look something like the following, in order:

  1. Verify that the correct torque settings are being used – 120Nm ok
  2. Verify the torque wrench – calibration ok
  3. Check fastener property class head marking – class 10.9 ok
  4. Check for any signs of lubrication which could have gotten into the threads or under the rotating bearing surface – ok
  5. Check the core hardness of the bolts – HRC 32-39 ok
  6. Consult your fastener supplier for a joint analysis

Real Life Assembly Solutions

This exact case happened to a Bossard engineer. After checking the screws to ensure that they met specifications for hardness, the obvious recommendation was to lower the torque. But by how much? How can we ensure enough clamp load to keep the joint tight?

In this case, the design engineer had determined a minimum clamp load requirement of 30kN for a safe joint. Since the recommended torque was causing the bolts to stretch, we performed a test to determine how much torque was necessary to tighten the joint.

By performing a torque/tension test on the joint, we were able to determine that the painted surface under the flange nut had much lower friction than predicted. This caused much higher clamp loads using the recommended torque of 120Nm.

Graph comparing clamp load with a painted surface, and a bare steel surface:

Typical data from the joint analysis:

  • MA = torque
  • FV = clamp load
  • µ coef = total coefficient of friction

More testing was necessary to determine at what torque yielding would occur. In the worst case, yielding occurred at 61kN clamp force, which is higher than the minimum 30kN requirement.

The joint analysis pointed out the issue and the recommendation was to lower the torque to 110Nm to stay above the minimum clamp load and below the yield point of the screws to avoid stretching and stopping the line. Problem solved!

How to Avoid Assembly Nightmares – Part 1

Solutions to Assembly Nightmares 1

Laser cutting sheet metal has some serious benefits in time savings and accuracy. It can also cause some headaches when cutting holes for direct fastener assembly.

For many years, manufacturers alike have used thread forming screws with standard machine screw threads and case-hardened special points. These screws use pre-made holes, forming their own threads into the mating material. The thickness of the material generally dictates the size of the hole needed to create the lowest driving torque and highest stripping torque which leads to the best joint performance.

Drilling or punching into mild steel creates holes for these screws. Hole size recommendations exist for each size and thickness of the material. But, when laser cutting holes, we often see the heat affected zone, which makes the surface of the material around the hole somewhat harder. If using standard hole recommendations for drilling or punching, problems can occur during assembly.

Common Assembly Problems:

  • Hard start – screws spin
  • High drive torque – gun will not seat screws
  • Breaking screws before seating

These problems usually show that the hole size is too small. With oversized holes, we often see threads stripping rather than achieving their assembly torque.

While it is difficult to provide recommended hole sizes for each material type, each thickness, and each method of preparation, performing a drive/strip torque test in a controlled environment may be the best way to ensure the best joint performance. Let’s look at an example of a test recently done by a Bossard engineer:

Plate steel provided by the customer with incrementally larger sizes of laser cut holes:

Graph of a typical test:

Graph of the average data for many hole sizes:

Typical summary data from one hole size:

By performing a joint analysis in our laboratory, we can recommend the proper hole size for your design to ensure optimal performance.

Where to Find Hidden Cost Savings in Your Fasteners

Hidden Cost Savings from Your Fasteners

Your design has been in production for a while, and now it’s time to look into cost savings. Fasteners are such a small fraction of the total design cost, is it worth looking for savings in this area?

While it’s true that the cost of the fastener may be small, there are many hidden costs that are often overlooked when purchasing hardware. We call this Total Cost of Ownership, or TCO.

To better explain the TCO model in fastening, we use the iceberg model.

Total Cost of Fastener Ownership


On average, the fastener itself makes up only around 15% of the total costs. The remaining 85% of the costs come from development, procurement, testing, inventories, assembly, and logistics. This chain of events is adding costs to the entire fastening ecosystem.

Let’s look at an example from the Bossard Cost Savings Calculator.
