How to identify the fastener
A photo helps, but dimensions and function are what confirm the right alternative.
- 01
Function of the joint
Define whether the element must fix, anchor, position, retain, join or allow frequent disassembly.
- 02
Thread and dimensions
Confirm metric or imperial system, diameter, pitch, usable length and head geometry.
- 03
Base material and environment
Review the substrate, corrosion exposure, temperature and material compatibility.
- 04
Material and coating
Select the steel grade or alloy and the finish required for the intended service.
