Frequently Asked Questions

What’s the standard thread pitch for M5 screws?

The most common coarse pitch is 0.8 mm. Some specialty applications use fine pitch — always confirm on the product page.

When should I use Low Head Socket vs. standard Socket Cap?

Low Head socket cap screws reduce head height for tight clearances. They offer less wrench engagement than standard DIN 912 socket caps, so use them where space is critical and torque is moderate.

How do Hex Cap Bolts differ from Socket Cap Screws?

Socket caps use an internal hex/Allen drive and cylindrical head (DIN 912). Hex cap bolts use an external hex head (DIN 933 full thread / DIN 931 partial), driven with a wrench or socket tool.

Does black oxide prevent rust?

Black oxide offers a mild protective layer and uniform dark finish. For moisture, outdoor, or chemical exposure, choose stainless steel.
