Frequently Asked Questions (FAQ):

Q: What nuts and washers fit these bolts?
A: Use 5/16 in. coarse-thread nuts and corresponding flat or lock washers for proper fit.


Q: Are these suitable for outdoor use?
A: Yes. The zinc plating offers corrosion resistance suitable for most outdoor environments; for coastal or highly corrosive areas, consider stainless steel.


Q: Do these bolts have full threads?
A: Yes, they are fully threaded along the 5-1/2 in. length.


Q: What tools are needed for installation?
A: Tighten with a wrench or socket on the nut side; the square neck seats into wood to hold the bolt head in place without a screwdriver.


Q: Can they be used with metal?
A: They can be used in pre-drilled metal with a nut and washer; ensure proper hole size for the 5/16 in. diameter.
