Metallics JG5HTB99 Bolts 5/16-18 x 5-1/2 G5 Hx Tap Blt (Jar 100)

A tap bolt is fully threaded, head to point, with no unthreaded shank. That's what separates the JG5HTB99 from a standard hex cap screw of the same 5/16-18 x 5-1/2 size, which carries a grip length. Choose the tap bolt when you need thread engagement across the whole 5-1/2 inches, for example into a tapped hole of unknown depth or through a thick stack of material. If your joint needs the shear strength of a solid shank across the shear plane, use a partially threaded hex cap screw instead.

No. The JG5HTB99 is bolts only, 100 to a jar. Order 5/16-18 hex nuts separately, plus flat washers and a lock washer or nylon insert nut if the joint will see vibration. Match the nut to the bolt's Grade 5 rating so the assembly isn't limited by the nut.

Grade 5 hex tap bolts are a plain steel strength class, and the JG5HTB99 record states the size, length, and grade but not a protective coating. For exposed exterior or damp locations, specify a fastener with a stated corrosion finish, hot dip galvanized or stainless, rather than relying on this one. Indoors, in dry electrical and equipment mounting work, it's the standard choice.

100 bolts, packed in a jar. The jar is the shop-counter pack Metallics uses for loose fasteners, so it stays sorted on a van shelf or a bench rather than loose in a bin. Order in multiples of the jar if you're stocking a service truck.

A standard 5/16-18 hex head takes a 1/2 inch wrench or socket. That's the normal across-flats size for this diameter in the inch series, so no special tooling is needed to set the JG5HTB99.
