Metallics JHHMS82 – Frequently Asked Questions
1) Is a 6-32 hex head slotted machine screw the same thing as a sheet metal or self tapping screw?
No. A machine screw like the JHHMS82 has a uniform 6-32 machine thread, 32 threads per inch, and needs an existing tapped hole or a nut; it will not cut its own thread. If you are fastening into bare sheet metal with no tapped hole, you want a self drilling or self tapping screw instead. For a tapped 6-32 hole in a box, bracket, or device strap, this is the correct screw.
2) What size wrench or driver fits the hex head on the Metallics JHHMS82 machine screw?
The head measures 0.244 to 0.250 inch across the flats, so a 1/4 inch wrench, nut driver, or socket is the fit. Head height runs 0.080 to 0.093 inch. It is also slotted across the top, so you can run it with a flat blade screwdriver where a wrench will not reach.
3) Is the hex head on this 6-32 screw wide enough to hold a washer or a ring terminal without one pulling through?
The bearing surface of the head is spec'd with a washer outside diameter of 0.302 to 0.328 inch, wider than the 0.250 inch across-flats dimension, so the hex head has a small integral washer face under it. That seats fine on a standard 6-32 ground hole or a ring terminal. For sheet metal or slotted brackets with larger openings, add a flat washer.
4) Are these hex slotted machine screws corrosion resistant enough for damp or outdoor junction boxes?
These are carbon steel with a zinc plating, which handles indoor and generally dry or occasionally damp locations. Zinc plated steel is not the choice for wet locations, coastal exposure, or washdown areas; use stainless 6-32 hardware there instead.
5) What dimensional standard do these Metallics hex head slotted machine screws meet?
They are made to ASME B18.6.3-2002, the standard for machine screws and tapping screws, with threads to ANSI/ASME B1.1. If a drawing or a facility spec calls out B18.6.3 hex head slotted machine screws, this meets that call-out.
6) How many screws come in a jar and what is the minimum I can order?
They ship in a jar of 100 pieces, and 100 count is the order minimum, so one jar is the smallest buy. The jar weighs 195 g. Other sizes and quantities can be had by request if 6-32 x 3/4 is not the length you need.
7) Do these screws qualify for a Buy American or ARRA funded job?
Metallics lists the JHHMS82 as Buy American compliant and ARRA compliant. Country of origin is coded as multiple, so if your contract requires a single named country of manufacture on the submittal, ask for the mill documentation on the specific lot.
