Metallics JMHTB416 – Frequently Asked Questions

1) What thread size and pitch is the Metallics JMHTB416 tap bolt?
It's an M4 bolt with a 0.7 mm thread pitch, right-hand thread, 16 mm long. M4 x 0.7 is the standard coarse metric pitch for a 4 mm diameter, so it mates with any standard M4 nut or tapped M4 hole.
2) Is the JMHTB416 fully threaded up to the head, or does it have a shoulder?
Fully threaded. The threads on the shank run all the way to directly beneath the head, which is what makes it a tap bolt rather than a partially threaded hex cap screw. It also has a washer face beneath the hex head, so it bears evenly without needing a separate washer for seating.
3) Can I use Metallics JMHTB416 bolts on a federally funded or Buy American job?
No. The JMHTB416 is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. If your project carries a domestic sourcing requirement, you'll need a domestically produced fastener instead.
4) Is the JMHTB416 a metric bolt or an inch bolt? I need to be sure before I tap the hole.
Metric. It's M4 x 16 with a 0.7 mm pitch, so tap for M4 coarse, not a #8-32 or any inch size. The two are not interchangeable even though M4 and #8 are close in diameter.
5) What does Class 8.8 mean on this metric hex tap bolt, and is it strong enough for mounting a motor?
Class 8.8 is medium carbon steel, heat treated, hardened to Rockwell C22-32. Metallics lists it at 11,600 psi minimum tensile and 92,800 psi minimum yield. It's the common grade for mounting motors to machinery and for automotive and truck repair work, which is exactly what Metallics calls out for this bolt.
6) Will a zinc plated steel bolt like this hold up outdoors or in a wet mechanical room?
The JMHTB416 is steel with a zinc finish. Zinc plating handles indoor and sheltered mechanical, plumbing, HVAC and electrical work, which is the field application Metallics lists for the series. For sustained wet exposure or washdown, step up to stainless rather than zinc plated carbon steel.
7) How many bolts come in a jar of Metallics JMHTB416, and can I buy a smaller quantity?
They ship in a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest buy. Jar weight is listed at 231 g. Metallics notes other sizes and quantities in the MHTB and JMHTB series are available by request.
8) What size wrench or socket do I need for these M4 hex tap bolts?
The hex head on an M4 Class 8.8 tap bolt takes a 7 mm wrench or socket, matching the 7 mm across-flats dimension Metallics lists for the head. Keep a 7 mm combination wrench and socket on the cart when you order a jar.
