Frequently Asked Questions
Q: Does it come with a screwdriver?
A: Includes a free Phillips bit made from premium S2 steel. You need your own drill or driver handle.
Q: Will these fit my myQ keypad?
A: Yes, many customers use them as direct replacement screws for myQ keypads and other home security devices.
Q: Will these rust?
A: No. 304 stainless steel with black oxide is corrosion-resistant for indoor and outdoor use.
Q: Are they magnetic?
A: 304 stainless steel is non-magnetic in its annealed state. However, cold forging (the process used to form our screws) can induce weak residual magnetism – this is normal for cold-worked stainless steel and does not affect corrosion resistance or performance. Completely safe for electronics.
