Metallics JG5HCF59 – Frequently Asked Questions
1) Is the Metallics JG5HCF59 bolt a coarse or fine thread?
Fine thread. The JG5HCF59 is a 3/8-24 hex bolt, 24 threads per inch, so it will not thread into a 3/8-16 coarse tapped hole or nut. Match it with 3/8-24 fine nuts or tapped holes only.
2) How strong is a grade 5 zinc hex bolt like the Metallics JG5HCF59?
It is a medium carbon steel cap screw, heat treated to grade 5, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Steel is per AISI 1008-1026 and dimensions follow ASME B18.2.1-2012. For higher clamp loads you would step up to grade 8.
3) Does the Metallics JG5HCF59 bolt meet Buy American and ARRA requirements for a government job?
Metallics lists this grade 5 hex bolt as both Buy American compliant and ARRA compliant, which is what public and institutional procurement usually needs on the submittal. Country of origin is listed as multiple.
4) Will a zinc plated grade 5 bolt hold up outdoors or in a damp mechanical room?
The JG5HCF59 is plated steel with a zinc chromate finish, which handles indoor and sheltered equipment duty well. It is not stainless, so continuous wet, coastal or washdown exposure will eventually corrode it. For those conditions specify stainless.
5) How many bolts come in a jar of Metallics JG5HCF59?
100 pieces per jar, and the jar is the minimum order quantity. The packed jar weighs 2195 g. Metallics notes other sizes and quantities are available by request.
6) Will the JG5HCF59 pass through a 3/8 inch clearance hole?
The shank outside diameter runs 0.3690 to 0.3750 inch, so it is a nominal 3/8 inch bolt and needs a clearance hole slightly over 3/8 inch, typically 13/32 inch. A drilled hole at exactly 0.375 will be tight or bind.
7) What is this 3/8-24 x 1-1/4 hex bolt typically used for?
Mounting motors to machinery is the common use, and it is also a staple in automotive and truck repair. The 1-1/4 inch length under the head suits thinner bolted joints; fine 24 TPI thread gives better holding in vibrating equipment.
