Good value bulk pack

Screws are good quality. One box had a few slightly bent ones but most were perfect.

Precise machining

The head height is consistent across all pieces. Fits my Allen keys perfectly without stripping.

5 FAQ

Q: Can I use these for marine applications?

A: While 304 is corrosion resistant, 316 grade is recommended for direct saltwater exposure.

Q: Do these come with matching nuts?

A: No, these are sold as screws only. Nuts are available separately.

Q: What Allen key size fits the M4 screw?

A: For M4 size, you will need a 3mm hex key.

Q: Are these magnetic?

A: A2-304 stainless steel is generally non-magnetic or slightly magnetic due to work hardening.

Q: Is the thread full length or partial?

A: These feature full threading along the shank for maximum grip.
