Metallics JG5HCF1 – Frequently Asked Questions
1) Is the Metallics JG5HCF1 hex bolt a fine thread or coarse thread 1/4 inch bolt?
Fine thread. The JG5HCF1 is a 1/4-28 bolt, 28 threads per inch, which is UNF rather than the more common 1/4-20 UNC. It will not thread into a 1/4-20 nut or tapped hole, so match it to fine-thread hardware only. Thread form is made to ASME B18.2.1-2012.
2) What strength does a Grade 5 hex cap screw like the JG5HCF1 give me?
Grade 5 medium carbon steel, heat treated: 120,000 psi minimum tensile and 92,000 psi minimum yield, with hardness of Rockwell C25-34. Material conforms to AISI 1008-1026. That is the normal choice for motor mounting and general machinery work where a Grade 2 bolt would be too soft.
3) Will the JG5HCF1 bolt pass through a 1/4 inch hole?
Shank outside diameter runs 0.2450 to 0.2500 inch, so it needs a clearance hole, not a straight 1/4 inch one. Standard practice is a 17/64 inch drill for a 1/4 inch bolt. Hole it tight at exactly 0.250 and the zinc-plated shank will bind.
4) What size wrench or socket fits the head on this 1/4-28 Metallics hex bolt?
The hex head measures 0.428 to 0.438 inch across the flats, so a 7/16 inch wrench or socket is the fit. Wrenching height is 0.106 inch, which means a thin or low-profile socket seats better in a tight recess than a deep chamfered one.
5) Is this bolt plated for corrosion resistance, and is it suitable outdoors?
The bolt is steel with a zinc finish, zinc chromate type plating. That handles indoor machinery, panel, and vehicle work and gives moderate protection in damp conditions. For sustained outdoor exposure, wash-down, or coastal service, stainless or hot-dip galvanized is the better call.
6) How are these Metallics Grade 5 hex bolts packaged and what is the minimum I can buy?
They come 100 pieces in a jar, and 100 count is the order minimum, so you buy by the jar rather than by the piece. Shipping weight of the jar is listed at 694 g. Other sizes and quantities are available by request.
7) Can I use these bolts on a federally funded or Buy American job?
Metallics lists the G5HC and JG5HC series as both ARRA compliant and Buy American compliant. Country of origin is recorded as multiple, so if your specification requires documented domestic melt and manufacture for a specific lot, request the certification with the order.
8) Do I need to order nuts and washers separately with the JG5HCF1?
Yes. The jar contains bolts only, 100 hex cap screws. Any nuts, flat washers, or lock washers are separate line items, and the nuts must be 1/4-28 fine thread to match. Pair Grade 5 bolts with a Grade 5 or higher nut so the nut is not the weak point.
9) What is this 1/4-28 x 3/4 hex cap screw typically used for?
Mounting motors to machinery is the main use, and it is common in automotive and truck repair where fine thread fasteners are the norm. The 3/4 inch length suits thin flanges and brackets where a longer bolt would bottom out or protrude; at that length the thread runs most of the shank, so grip length is short.
