Metallics G5HC39 – Frequently Asked Questions
1) Does the G5HC39 come with nuts and washers?
No. It's bolts only, 25 per box, so order nuts and flat or lock washers separately. You'll want 1/2-13 coarse-thread nuts and 1/2 inch washers to match. Other sizes and pack quantities in the same Grade 5 hex bolt line are available by request.
2) What wrench or socket size fits this 1/2-13 hex bolt head?
Across the flats the head measures 0.736 to 0.750 inch, so a 3/4 inch socket or wrench is the right tool. Corner-to-corner the head runs 0.840 to 0.866 inch, which is what matters if you're driving it inside a counterbore or a tight pocket on a motor base.
3) Will zinc-plated steel bolts hold up outdoors?
The G5HC39 is zinc-plated carbon steel. Zinc handles indoor mechanical rooms, equipment pads, and general shop work, and gives moderate protection in sheltered outdoor use. For sustained wet exposure, coastal air, or chemical service, step up to hot-dip galvanized or stainless; zinc plating will eventually give up its sacrificial layer and the steel underneath will rust.
4) Do these Metallics Grade 5 bolts meet Buy American requirements on a public project?
The G5HC39 carries Buy American and ARRA compliance flags in its product record, though country of origin is listed as China. On a federally funded job where the specification requires domestic material, submit the manufacturer's certification for the lot you receive before installing.
5) Is the minimum order 25 pieces, or can I buy these hex bolts individually?
They ship as a box of 25. The count is the order minimum, so 25 pieces is the smallest quantity of the 1/2-13 x 4-1/2 Grade 5 bolt you can buy. Larger quantities and other lengths in the same series are available on request.
6) What dimensional standard do these hex bolts conform to?
Thread and head geometry follow ASME B18.2.1-2012, the standard for square and hex bolts and screws, and the steel is within the AISI 1008-1026 range. That means the head will match standard hex socket sizes and the bolt will drop into prep laid out to B18.2.1 dimensions.
7) How much does a box of 25 of these 1/2-13 x 4-1/2 bolts weigh?
7.06 lbs for the box of 25. Useful if you're pricing freight or loading a service truck with several boxes.
