Metallics JG5HCF4 – Frequently Asked Questions
1) Is the Metallics JG5HCF4 bolt a fine thread or coarse thread 1/4 inch bolt?
Fine thread. The JG5HCF4 is a 1/4-28 bolt, 28 threads per inch, which is UNF rather than the more common 1/4-20 coarse (UNC) thread. A 1/4-20 nut or tapped hole will not accept it, so match the tapped hole or nut to 28 TPI before ordering. Thread conforms to ASME B18.2.1-2012.
2) What grade and strength is this 1/4-28 x 2 hex bolt rated for?
It is a Grade 5 hex cap screw: medium carbon steel, heat treated, with 105,000 psi minimum tensile and 105,000 psi minimum yield, and hardness of Rockwell C19-30. Steel is to AISI 1008-1026. That puts it well above a plain Grade 2 fastener for motor mounting and machinery work, but below a Grade 8 if your drawing calls one out.
3) What wrench or socket size fits the head on the Metallics JG5HCF4?
Head width across flats measures 0.428 to 0.438 inch, so a 7/16 inch wrench or socket is the fit. Corner-to-corner width runs 0.488 to 0.505 inch. The head is a standard hex.
4) How many bolts come in a jar of Metallics JG5HCF4, and can I buy fewer?
They ship as a jar of 100, and 100 count is the order minimum, so a jar is the smallest buy. Full jar weight is 1393 g. Metallics notes other sizes and quantities are available by request.
5) Will a zinc plated Grade 5 bolt hold up outdoors or in a damp mechanical room?
The JG5HCF4 carries a zinc plated finish over steel, which handles indoor and sheltered mechanical room conditions and incidental moisture. For continuous wet, coastal, or washdown exposure, zinc plating on carbon steel is not a long-term corrosion answer; specify stainless or hot dip galvanized for those openings instead.
6) Is the Metallics JG5HCF4 bolt Buy American and ARRA compliant for a government job?
It is flagged compliant for both Buy American and ARRA. Country of origin is listed as multiple, so if your submittal requires a single named country of manufacture, request the cert for the lot you are being shipped.
7) What is this 1/4-28 x 2 inch Grade 5 hex bolt typically used for?
It is a hex cap screw commonly used to mount motors to machinery, and it sees heavy use in automotive and truck repair where fine thread fasteners are the norm. The 2 inch length is measured under the head, with a shank diameter of 0.2450 to 0.2500 inch, so figure your grip plus enough thread engagement into the tapped hole or nut.
8) How much head height does the JG5HCF4 add above the mounted surface?
Head height runs 0.150 to 0.163 inch, with 0.106 inch of wrenching height on the flats. That matters when the bolt sits in a recessed pocket or under a guard, there has to be enough clear depth for a socket to engage the 0.106 inch wrenching surface.
