Metallics G5HTB75 – Frequently Asked Questions
1) What thread does the Metallics G5HTB75 hex tap bolt use, and is it fully threaded?
It's a 5/8-11 right hand thread, 11 threads per inch, made to ASME B18.2.1-2012. Being a tap bolt, the thread runs the full 5 inch length rather than stopping short like a cap screw with a grip length, so it will thread all the way into a tapped hole or through a nut at any depth.
2) Will a 5/8-11 bolt pass through a 5/8 inch drilled hole?
The shank outside diameter runs 0.6170 to 0.6250 inches, which is at or just under nominal 5/8. A hole drilled at exactly 0.625 leaves effectively no clearance, so use a 11/16 inch clearance hole for a through-bolted joint. For a tapped hole, 5/8-11 is the standard coarse thread.
3) What wrench size fits the head on this 5/8-11 Grade 5 tap bolt?
Head width across flats measures 0.922 to 0.938 inches, so a 15/16 inch wrench or socket is the right fit. Head height is 25/64 inch, with a wrenching height of 0.269 inch - worth knowing if you're working in a counterbore or tight pocket where socket engagement is limited.
4) Can these zinc plated steel tap bolts be used outdoors or in a damp mechanical room?
Finish is zinc on steel, which handles indoor and sheltered mechanical room service and gives moderate corrosion resistance. Zinc plating is a sacrificial coating and will eventually corrode in constant wet, salt spray, or exterior exposure - for those conditions specify 18-8 stainless or hot dip galvanized instead.
5) How many bolts come in a box of Metallics G5HTB75, and can I buy fewer?
They ship as a box of 50 pieces, and 50 count is the order minimum, so partial boxes aren't broken. Metallics notes other sizes and quantities in the G5HTB series are available by request if 5/8-11 x 5 isn't the length you need.
6) Do these bolts meet Buy American or ARRA requirements on a public project?
The G5HTB75 is flagged compliant for both ARRA and Buy American, with country of origin listed as China. On federally funded work, verify which standard your contract actually invokes, since the applicable rule differs between ARRA, the Buy American Act, and Build America Buy America.
7) Does a hex tap bolt come with nuts and washers?
No. The box contains 50 bolts only - no nuts, flat washers, or lock washers. If you're through-bolting rather than threading into a tapped hole, order 5/8-11 hex nuts and 5/8 washers separately, and match the nut grade to the bolt so the joint isn't limited by the nut.
8) What is the shipping weight of a 50 count box of 5/8-11 x 5 Grade 5 tap bolts?
A full box runs 21.3 lbs, with carton dimensions of 7.25 x 6.25 x 6 inches. Useful if you're staging several boxes for a jobsite delivery or figuring out what a tech can reasonably carry up to a rooftop unit.
9) What steel are Metallics Grade 5 hex tap bolts made from?
Medium carbon steel to AISI 1008-1026, heat treated to reach Grade 5 properties. That material and the Rockwell C19-30 hardness are what let it be torqued to Grade 5 values without the thread deforming, unlike an unhardened low carbon Grade 2 bolt of the same size.
