All of our products are manufactured for reliability and consistently high quality and are RoHS compliant as standard.
Our bright zinc based platings are all high quality trivalent clear chromate based finishes.
Poor performance - (part not fully installed)
Poor performance - (part not installed squarely)
Poor performance - (wrong hole size punched in panel)
Poor performance - (hole has been deburred)
Tight Threads - (part has been over installed)
Part is cracking on installation - (wrong shank length used)
Stud is buckling panel - (need countersink in anvil)
Head of fastener is cupping - (punch is too narrow)

The following are examples of the most common forms of installation problem.
Click on the links below for pictorial explanations and solutions.
The minimum centerline to edge limits as outlined in the data sheets on this site were generally determined by installing parts into 1.5mm aluminium, without a bulge forming at the panel edge.
When installing very close to the edge of the panel, any formed bulge will result in a reduced performance and the centerline of the fastener will move toward the edge (causing later hole misalignment problems).
Using a thicker panel will allow for installation closer to the edge. (Conversely thinner sheets require a greater distance).
Using a nut with a shorter shank length will allow closer edge distance.
If you really need to install very close to the edge (closer than recommended) then:
Put up with the bulge and the reduced performance.
Make a bracket to hold the edge of the panel (see here).
Speak to our technical department to discuss your application. (We may be able to design a special fastener to suit your application).
