Metallics JFM84 – Frequently Asked Questions

1) Does the flat head on this 8-32 screw sit flush, and what countersink does it need?
The JFM84 has a flat head, which seats flush in a countersunk or chamfered hole rather than sitting on the surface. Head width runs 0.285 to 0.312 in. and head height 0.084 to 0.1 in., built to ASME B18.6.3-1998, so it drops into any standard 82-degree countersink sized for a #8 flat head. If your hole is not countersunk, use a round or pan head instead so the head bears on the surface.
2) Will these Metallics screws meet a Buy American requirement on a government or federal job?
No. The JFM84 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your project carries a domestic sourcing clause, you need a US-made fastener instead.
3) Can I drive these 8-32 screws with a power driver, or do I need a hand screwdriver?
The JFM84 is slotted drive, not Phillips or combo, with a slot 0.045 to 0.054 in. wide and 0.029 to 0.045 in. deep. A slot cams out easily under a power driver, so hand driving with a properly sized flat-blade is the safer bet. If you want to run them with a drill, pick a Phillips or combination-head #8-32 instead.
4) Are these zinc machine screws strong enough for mounting a heavier device or bracket?
Each screw carries an 850 lb minimum tensile strength with hardness at Rockwell B70-B100, made from AISI 1006-1022 low carbon steel. That is ample for device, plate, and light bracket mounting. For structural or high-load connections, move up to a graded bolt rather than a low carbon machine screw.
5) Is a zinc plated steel machine screw okay for outdoor or damp locations?
The JFM84 is zinc plated steel, which is a dry-location and indoor-protected finish. Zinc gives mild corrosion resistance but will eventually rust in wet, exterior, or washdown service. For damp, corrosive, or coastal work, specify a stainless 8-32 flat head slotted screw instead.
6) What trades use the Metallics FM series 8-32 flat head machine screws?
The FM and FMP series is stocked for electrical, plumbing, and heating and air conditioning work, so it is a general MRO fastener for panel, device, duct accessory, and equipment mounting where an 8-32 thread is called for.
