Metallics JG5HC4 – Frequently Asked Questions
1) What thread and size are the Metallics JG5HC4 hex bolts, and will they take a standard 1/4-20 nut?
The JG5HC4 is a 1/4-20 hex cap screw, 2 inches long, with 20 threads per inch and a shank outside diameter of 0.2450 to 0.2500 inch. It is made to ASME B18.2.1-2012, so it mates with any standard 1/4-20 UNC nut or tapped hole.
2) Is the JG5HC4 strong enough to mount a motor to a machine base?
That is the use it is built for. It is a Grade 5 medium carbon steel cap screw, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Metallics lists motor-to-machinery mounting as a primary application, along with automotive and truck repair.
3) Are these Metallics hex bolts Buy American or ARRA compliant for a government job?
No. The JG5HC4 is not Buy American compliant and is not ARRA compliant, and the country of origin is listed as multiple. If your spec carries a domestic sourcing requirement, this bolt will not satisfy it.
4) What size wrench or socket fits a 1/4-20 Grade 5 hex bolt like the JG5HC4?
Head width across flats measures 0.428 to 0.438 inch, which is the standard 7/16 inch hex for a 1/4-20 cap screw. A 7/16 socket or open-end wrench drives it.
5) How many bolts come in a jar of Metallics JG5HC4, and can I buy fewer?
The JG5HC4 ships as a jar of 100 bolts, and the jar is the order minimum unit, so 100 pieces is the smallest quantity. Metallics notes other sizes and quantities are available by request.
6) Will zinc plated Grade 5 bolts hold up outdoors or in a damp mechanical room?
The JG5HC4 is plain carbon steel with a zinc plated finish. That handles indoor mechanical rooms, panel work, and HVAC equipment fine, but zinc plating is a sacrificial coating and will eventually corrode in direct weather exposure or wet/chemical environments. For sustained outdoor or wash-down duty, step up to stainless or hot dip galvanized.
7) Is a 2 inch long 1/4-20 bolt the right length for my application, or do I need to account for grip?
At 2 inches of overall length under the head, the JG5HC4 suits assemblies where combined material thickness plus nut and washer stack stays under that. Hex cap screws in this length are partially threaded, so if you need full thread engagement right up to the head on a thick stack, size the length to your grip rather than assuming threads run the full 2 inches.
8) What grade of steel are these 1/4-20 hex cap screws made from?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to Grade 5. That is the standard medium carbon spec behind a Grade 5 cap screw and is why it carries 105,000 psi minimum tensile.
9) Are these bolts appropriate for electrical and HVAC trade work?
Yes. Metallics lists the field application for the G5HC/JG5HC series as the electrical, plumbing, heating and air conditioning industries, which covers equipment mounting, strut and bracket work, and unit anchoring in those trades.
