Frequently Asked Questions (FAQ):

Q: What wrench or socket size should I use?
A: Use a wrench or socket sized for 5/16 in. hex bolt heads; check your tool set for the matching SAE size.


Q: Are these bolts suitable for outdoor use?
A: The zinc-plated finish offers moderate corrosion resistance for indoor and light outdoor applications; for harsh environments, consider galvanized or stainless steel.


Q: What nuts should I pair with these bolts?
A: Use 5/16-18 coarse-thread nuts and matching washers to ensure proper fit and load distribution.


Q: Is drilling required before installation?
A: Install into appropriately sized pre-drilled holes or tapped threads; ensure the hole matches 5/16-18 coarse thread specifications.


Q: Can these be used for high-stress structural applications?

Top quality for the price but a little tight in the toe box
Size: 8.5, Color: Black Full Grain
A little tight around the toe box for me and I don’t have a particularly wide foot. But the quality is great and the look is awesome. Hoping they stretch out a bit with some wear!
