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?
A: These are Grade 2 low carbon steel bolts, intended for general-purpose fastening, not high-strength structural uses.

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.
