FAQ(s)

   What is a cap screw used for?

Capscrews are used to fasten components securely in optical systems, mounts, and mechanical assemblies where precision and durability are necessary.

   What's the difference between a cap screw and a bolt?

A cap screw is designed to fit tightly into a tapped hole and often provides a cleaner, more secure fit than a standard bolt. Unlike bolts which are tightened using a nut, socket head cap screws have a hexagonal socket making it easy to secure using an Allen wrench.

   What materials are these cap screws made of?

Edmund Optics' cap screws are typically manufactured from alloy steel for corrosion resistance and strength in lab or production environments.

   Are socket head cap screws reusable?

Yes, if not damaged or over-torqued, they can be reused repeatedly. Always check thread integrity and apply proper torque when reassembling.
