Metallics JHHMS96 – Frequently Asked Questions
1) Do these Metallics fasteners qualify on a Buy American or ARRA funded job?
Metallics lists the JHHMS96 as both ARRA compliant and Buy American compliant. Country of origin is China, so confirm which clause your contract actually invokes before submitting, since some federal provisions turn on domestic melt and manufacture rather than compliance coding.
2) Can I drive these hex head machine screws with a screwdriver instead of a wrench?
Yes. The JHHMS96 has a slotted hex head, so a flat blade driver handles it in tight spots like the back of a panel or a box where a 9/16 socket will not fit. For final torque a wrench on the hex gives you more control.
3) Are these zinc plated screws OK for damp or outdoor electrical work?
The JHHMS96 is steel with a zinc finish. Zinc plating handles indoor and sheltered conditions and incidental moisture, but it is not a marine or sustained wet finish. For permanently exposed outdoor or washdown locations, specify stainless steel instead.
4) How many screws come in a jar of Metallics JHHMS96, and can I buy less than a full jar?
They ship 100 to a jar, and 100 count is the order minimum, so the jar is the smallest unit. Other sizes and quantities are available by request.
5) What dimensional standard do these hex head machine screws follow, for spec submittals?
Head and body dimensions are built to ASME B18.6.3-2002, with threads to ANSI/ASME B1.1. That pairing is what a submittal reviewer looks for on a slotted hex head machine screw, and it means the head will match standard 9/16 tooling and clearance callouts.
6) What washer size do I need with the 3/8-16 JHHMS96 screws?
The matching washer outside diameter is 0.720 to 0.780 inches. Washers are not included with the jar, so order them separately if your assembly needs them.
