Metallics JG5HTB90 – Frequently Asked Questions
1) Do these Metallics hex tap bolts meet Buy American or ARRA requirements on a federal job?
Metallics lists the JG5HTB90 as compliant for both Buy American and ARRA. Country of origin is China. If your contract carries a domestic-melt or domestic-manufacture clause rather than a general Buy American compliance flag, confirm which standard the spec is written to before you submit it.
2) What wrench or socket size fits the head on a 5/16-18 Grade 5 hex tap bolt?
Head width across flats is 0.489 to 0.500 inch, which is a 1/2 inch wrench or socket. Head height is 13/64 inch with 0.14 inch of wrenching height, so it needs very little clearance above the surface. Across corners the head measures 0.557 to 0.577 inch if you're checking counterbore or recess clearance.
3) Are these zinc plated bolts okay for outdoor or damp locations?
The finish is zinc over steel, which handles indoor and sheltered conditions and incidental moisture. For constant wet exposure, washdown, or coastal work, step up to 18-8 stainless hex tap bolts instead; zinc plating will eventually corrode through in those environments.
4) How many bolts come in a jar of Metallics JG5HTB90, and can I get a smaller quantity?
100 bolts per jar, and 100 count is the order minimum, so the jar is the smallest unit sold. The jar packaging holds up better on a service truck than a poly bag. Metallics does make other sizes and quantities in the G5HTB and JG5HTB hex tap bolt series on request.
5) Does a hex tap bolt need a nut, or does it thread into the part?
Threaded full length, a tap bolt is made to thread directly into a tapped hole, which is why it's the common choice for bolting a motor base to a machine frame. It will also work with a nut and washers through a clearance hole. Nuts and washers are not included with the jar, so order them separately in 5/16-18.
6) What steel are Metallics Grade 5 hex tap bolts made from?
Carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties, then zinc plated. Shipping weight on a jar of 100 is 1,873 grams.
