Metallics JG5HC88D – Frequently Asked Questions
1) What thread does the Metallics JG5HC88D 3/8 hex bolt take, and will it run into a standard 3/8-16 tapped hole?
It's a 3/8-16 coarse thread, 16 threads per inch, made to ASME B18.2.1-2012 for hex bolt dimensions. Shank outside diameter runs 0.3690 to 0.3750 in., so it threads into any standard 3/8-16 UNC tapped hole or takes a standard 3/8-16 nut.
2) Is this 3/8-16 hex bolt long enough to mount a motor base, or do I need a longer screw?
The JG5HC88D is a 1/2 in. long bolt, so it suits a tapped hole or a thin foot where total grip is under about half an inch. Stack a flange, washer and nut on it and you'll run out of thread fast. Metallics builds the same G5HC and JG5HC Grade 5 hex cap screw line in other lengths and diameters, so order the longer length for thicker clamp-ups.
3) Does this bolt qualify for a Buy American or ARRA-funded job?
Yes. The Metallics JG5HC88D Grade 5 hex bolt is made in the United States and flagged compliant for both Buy American and ARRA requirements, which is what a public-agency or federally funded project submittal will ask for.
4) What wrench or socket size fits the head on this Metallics Grade 5 hex cap screw?
Head width across flats measures 0.551 to 0.562 in., which is a 9/16 in. wrench or socket. Head height is 15/64 in., with 0.16 in. of wrenching height, so a standard six-point socket gets full purchase even in a tight pocket.
5) How many bolts come in a jar of Metallics JG5HC88D, and can I buy fewer?
They come 100 to a jar, and 100 count is the order minimum, so the jar is the smallest buy. Total shipped weight of the jar is 1306 g.
6) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The plating here is zinc, which handles indoor and sheltered service and resists the ordinary humidity of a plant floor or mechanical room. For constant wetting, coastal exposure, or washdown, zinc plated steel is the wrong pick and you want stainless or hot dip galvanized instead.
7) What is this 3/8-16 hex cap screw normally used for?
Mounting motors to machinery is the common job, and it also sees heavy use in automotive and truck repair. It's a hex cap screw, not a structural bolt and not a lag, so it pairs with a tapped hole or a nut, and you supply your own nuts and washers.
