Frequently Asked Questions

What is a Tamper Resistant Screw #8 size used for?

A Tamper Resistant Screw #8 size is used in security-sensitive applications where standard screws could be removed by unauthorized personnel.

What are the specifications of the Tamper-Pruf Screw 51390?

The Tamper-Pruf Screw 51390 is a #8 size, 3/4 in long, stainless steel flat head sheet metal screw with a plain finish. It features a tamper-resistant hex drive with a 5/32 in drive size and comes in a 25-pack. The stainless steel construction provides corrosion resistance for demanding environments.

How to install a tamper-resistant hex screw?

To install a tamper-resistant hex screw, use a matching tamper-resistant hex driver bit (5/32 in for this screw). Drive the screw straight into a pre-drilled pilot hole, applying steady pressure to avoid cam-out. Ensure the fastener is fully seated for a secure, flush finish in sheet metal or similar materials.
