Metallics JG9HC21 – Frequently Asked Questions
1) Do nuts or washers come with the Metallics JG9HC21 bolts?
No. The jar contains the 1/2-13 x 1-1/2 Grade 9 hex cap screws only. Order 1/2-13 coarse nuts and 1/2 inch flat or lock washers separately to complete the assembly, and match the washer hardness to the bolt grade so the washer does not deform under the higher clamp load a Grade 9 can generate.
2) What does Grade 9 mean on a hex cap screw, and is it stronger than Grade 8?
Grade 9 is a structural-grade bolt specification above Grade 8 in tensile strength, used where the connection is carrying high clamp load or shear. The JG9HC21 is a Grade 9 hex cap in 1/2-13 x 1-1/2, so if a drawing calls out Grade 5 or Grade 8 at that size, this exceeds it rather than falls short. Going the other way, if the spec calls for Grade 9 specifically, a Grade 8 substitute is not equivalent.
3) Will a 1-1/2 inch long bolt be long enough for my connection?
The JG9HC21 gives you 1-1/2 inches of length under the head. Figure your total stack: material thickness plus washers plus nut height. At 1/2-13 coarse, a standard hex nut eats roughly 7/16 inch of that, so you are realistically clamping about an inch of material before the threads run out. For thicker stack-ups, step up to a longer 1/2-13 cap screw instead.
4) Is the Metallics JG9HC21 a hex head bolt or a socket cap screw?
Hex head. It is a hex cap screw, driven with a wrench or socket across the flats, not an Allen key. For 1/2-13 hex cap screws the usual drive is a 3/4 inch socket.
5) What part number do I order for the Metallics 1/2-13 x 1-1/2 Grade 9 hex cap?
JG9HC21 is the Metallics number. The leading J in the part number corresponds to the jar pack of 25; if you are standardizing a stockroom bin, that is the number to put on the reorder card.
