Metallics G5HTB66 – Frequently Asked Questions
1) What thread size and pitch is the Metallics G5HTB66 hex tap bolt?
It's a 5/8-11 bolt: 5/8 inch nominal diameter with 11 threads per inch, right-hand thread, which is standard UNC coarse for that diameter. Measured shank outside diameter runs 0.6170 to 0.6250 in. Threading conforms to ASME B18.2.1-2012, so it mates with any standard 5/8-11 UNC nut or tapped hole.
2) Is a tap bolt fully threaded, or does it have a plain shank like a hex cap screw?
A hex tap bolt is threaded the full length of the shank, which is what separates it from a partially threaded hex cap screw. That matters when you're bolting into a tapped hole and want thread engagement all the way down, as with mounting a motor to a machine frame. If your joint needs an unthreaded grip length through a clearance hole to take shear, use a partially threaded hex cap screw instead. The G5HTB66 is the 5/8-11 x 2-1/2 size.
3) Can these zinc plated tap bolts be used outdoors or in a wet location?
The finish is zinc plating over steel, which handles indoor and sheltered outdoor service but is not a marine or continuously wet answer. For washdown, coastal, or corrosive environments, step up to 18-8 stainless hex tap bolts in the same 5/8-11 size. Zinc plated carbon steel in direct contact with aluminum or stainless in a wet joint will also invite galvanic corrosion.
4) How many bolts come in a box of Metallics G5HTB66, and can I buy fewer?
They ship 50 to a box, and 50 count is the order minimum, so it's a full-box purchase rather than loose pieces. Other sizes and quantities are available by request.
5) Do Metallics G5 hex tap bolts meet Buy American requirements on a public job?
The record shows both ARRA compliant and Buy American compliant flags, with country of origin listed as China. Bring both facts to your specifying authority, since agencies treat the Buy American provision and the actual origin differently depending on the funding source and the waiver in place.
6) What steel is used in these Grade 5 tap bolts, and will they take welding or re-plating?
Material is carbon steel to AISI 1008-1026, heat treated to reach Grade 5 properties. Because the strength comes from heat treatment, welding or any process that adds heat will draw the temper and drop the rated 105,000 psi minimum tensile. Same caution on re-plating: hydrogen embrittlement is a real risk on heat treated fasteners in this hardness range.
7) How much does a box of 50 of the 5/8-11 x 2-1/2 tap bolts weigh for shipping?
The packed box is listed at 12.83 lbs, with carton dimensions of 7.25 x 6.75 x 3.25 in. Useful if you're staging multiple boxes for a truck or figuring a freight line item on a bulk fastener order.
