Metallics JMHTB630 – Frequently Asked Questions

1) Is the Metallics JMHTB630 threaded all the way to the head, or does it have a plain shank?
Full thread, right up to directly beneath the head. That is what makes it a tap bolt rather than a partially threaded hex cap screw, and it is why it works for blind tapped holes where you need thread engagement at any depth. Thread direction is right hand.
2) What size and thread pitch is the M6 x 30 Metallics hex tap bolt?
It is an M6 diameter bolt with a 30mm length and a 1mm thread pitch, which is the standard coarse metric pitch for M6. If your tapped hole or nut is M6 x 1.0, this threads straight in.
3) Is a Class 8.8 bolt strong enough to mount a motor to machinery?
Class 8.8 is the common medium-strength metric grade and this bolt is rated at 120,350 psi minimum tensile and 95,700 psi minimum yield, with a hardness of Rockwell C23-34. Metallics lists motor mounting to machinery as its primary use, along with automotive and truck repair. For higher-load joints you would step up to Class 10.9.
4) Does the Metallics hex tap bolt have a washer face under the head, or do I need to add a flat washer?
There is a washer face formed beneath the hex head, which gives a flat bearing surface against the part. That does not replace a washer where you are clamping soft material, slotted holes, or oversized holes, but on a machined face it seats on its own.
5) Will a zinc plated steel bolt hold up outdoors or in a damp plant?
The JMHTB630 is medium carbon steel with a zinc finish, which is a general indoor and sheltered-use coating. It handles shop, plant, and equipment work, but for sustained wet exposure or washdown areas stainless or hot-dip galvanized is the better call.
6) How many bolts come in a jar of the Metallics JMHTB630, and can I buy fewer?
It ships as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. Metallics does offer other sizes and quantities in the MHTB and JMHTB series by request if a 100-piece jar is not the quantity you need.
7) Is the Metallics JMHTB630 hex tap bolt Buy American and ARRA compliant for a government job?
Metallics lists the JMHTB630 as both ARRA compliant and Buy American compliant. Country of origin is multiple, so if your contract requires documented origin on a specific lot, get that confirmed against the shipment.
8) How much does a jar of 100 M6 x 30 Metallics tap bolts weigh for shipping?
The jar of 100 is listed at 758 g. Useful if you are totaling out a parts order against a freight or handling limit.
