Metallics G5HC154 – Frequently Asked Questions
1) What thread and size is the Metallics G5HC154 hex bolt, and will a standard 7/8-9 nut fit it?
The G5HC154 is a 7/8-9 coarse thread bolt, 4 inches long, so any standard 7/8-9 UNC nut threads onto it. Thread count is 9 per inch and the shank outside diameter runs 0.8660 to 0.8750 inch. Dimensions follow ASME B18.2.1-2012, which is why it mates with off-the-shelf 7/8 hardware.
2) Is a Grade 5 bolt strong enough for mounting a motor to a machine base?
Grade 5 is the medium carbon, heat treated class, rated at 105,000 psi minimum tensile and 105,000 psi minimum yield, with hardness of Rockwell C19-30. Metallics lists motor mounting to machinery as a primary use for the G5HC series, along with automotive and truck repair. For higher clamp loads on a structural or high vibration connection, step up to a Grade 8 bolt instead.
3) Can I use the Metallics G5HC154 on a Buy American or ARRA funded project?
Metallics flags the G5HC154 as compliant for both ARRA and Buy American requirements. Country of origin is listed as multiple, so if your specifier needs a single documented origin for a given lot, confirm it on the shipment paperwork.
4) How many bolts come in a box of Metallics G5HC154?
They ship 25 to a box, and 25 each is the order minimum. Metallics notes other sizes and quantities in the G5HC series are available by request.
5) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The G5HC154 is steel with a zinc finish, which handles indoor and sheltered mechanical spaces well but is not a marine or continuously wet duty coating. For direct weather exposure or washdown areas, specify a hot dip galvanized or stainless 7/8-9 bolt instead.
6) How much material will a 4 inch long 7/8-9 bolt clamp?
Overall length is 4 inches measured under the head, and the head adds 35/64 inch of height above the surface. Subtract your nut and washer stack from the 4 inches to get usable grip. If the bolt bottoms out before the joint is tight, go to a longer length in the G5HC series rather than adding washers to make up the difference.
7) Are these hex bolts suitable for electrical and HVAC equipment mounting?
Yes. Metallics lists the field application for this Grade 5 hex bolt as the electrical, plumbing, heating and air conditioning trades, which is where the 7/8-9 x 4 size typically ends up anchoring motors, compressors and equipment bases.
8) What does a box of 25 of these 7/8 inch bolts weigh for freight?
A full box of 25 comes in at 17.92 lbs. Worth knowing if you are staging several boxes on a lift or planning a parts run.
