Riveting and Blind Bolting Systems - A Guide To Use

ALL FIT-LOCK products are tested by the manufacturers randomly using correct test procedures. FIT-LOCK STSTEMS LTD. Recommends that you use the data on this web site as a guide only. We strongly recommend that you test the fastener/tooling in/on your application to determine the exact performance you require.

We reserve the right to change dimensions and specifications without prior notice.

Our products offer a safe and economical solution to many fastening problems. They can be installed where there is no access to the blind side of your application. Installation is fast, tooling costs are low, and this gives high operator productivity.

The best choice for any application depends on the job itself. Is it going to be in damp conditions? How thick is the material being joined? How much of a load will each fastener carry? Identify your needs, then choose the style, type and size from our range to best suit your application.

Stength
Determine the shear and tensile strengths required for your application and then select the best product to meet that requirement. Style, material, diameter and fastener spacing all contribute to the ability of a fastener to hold the material properly.

Material
Select a fastener that is made of a similar or compatible metal to the material you are joining. Another factor to consider is the environment in which the finished products will be placed. For example, will the fastener be left in damp conditions, in high temperatures, or in a corrosive atmosphere?

Plating Specification
In September 2000, the European Union issued an End Of Life Vehicle Directive (ELV) (2000/53/EC). Products supplied from the 1st July 2007 shall not contain Hexavalent Chromium (Cr6+) in any type of plated product.

We have implemented this into our own system and all our plated products will be Cr6+ free as from the 1st July 2007. Should you require any information on alternative plating types it is recommended you contact our technical sales department.

Hole Size
It is extremely important that the hole size be correct to ensure that our fasteners perform properly.

Material Thickness
Measure the total thickness of the material to be fastened in order to determine the required grip of the fastener. Be sure to select a grip range sufficient to allow the secondary head of the fastener to form properly.

Head Style
The low profile dome head is appropriate for most applications. However, when soft or brittle materials are fastened to a rigid backing, the large flange head should be considered because it offers a greater bearing surface. Where a flush surface is required, the countersunk head style should be selected.
