Metallics JG9HC1 – Frequently Asked Questions
1) What thread size and length is the Metallics JG9HC1 hex cap screw?
The JG9HC1 is a 1/4-20 x 1/2 inch hex cap screw. The 1/4-20 means a 1/4 inch diameter with 20 threads per inch, which is the standard UNC coarse thread for that diameter, so it mates with any standard 1/4-20 nut or tapped hole. The 1/2 inch is the shank length under the head.
2) Will a 1/2 inch long 1/4-20 bolt be long enough for my bracket?
At 1/2 inch of shank under the head, the JG9HC1 suits thin stack-ups: roughly 1/4 inch of material plus a nut, or a tapped hole where you want around three to four threads of engagement without bottoming out. If you are clamping two pieces of strut, a plate plus a washer set, or anything approaching 1/2 inch combined thickness, step up to a longer 1/4-20 cap screw instead.
3) How many bolts come in a jar of Metallics JG9HC1?
Each jar holds 25 of the 1/4-20 x 1/2 inch Grade 9 hex cap screws. The jar pack is the sell unit, so order by the jar rather than the piece when you are stocking a truck or a shop bin.
4) What does Grade 9 mean on a hex cap screw, and is it stronger than Grade 8?
Grade 9 is a higher strength class than Grade 8 structural fasteners, used where joint loads or vibration would overstress a Grade 5 or Grade 8 bolt. The JG9HC1 is a Grade 9 hex cap screw in 1/4-20 x 1/2 inch, so it is the pick when a drawing or equipment spec calls out Grade 9 specifically. If your spec only calls for Grade 5 or Grade 8, a Grade 9 bolt still meets the minimum, but do not substitute downward.
5) Is this a bolt or a machine screw, and does it need a nut?
The JG9HC1 is a hex cap screw, meaning a hex head driven with a wrench or socket rather than a screwdriver. It can be run into a 1/4-20 tapped hole on its own or paired with a 1/4-20 nut and washers. Nuts and washers are not part of the jar of 25.
6) Are Metallics JG9HC1 bolts meant for electrical work?
Yes. These 1/4-20 x 1/2 inch Grade 9 hex cap screws are stocked as electrical fasteners, the hardware electricians use for mounting enclosures, strut, brackets and equipment. The jar of 25 is sized for shop and van stock rather than bulk structural work.
