Metallics JSBH55 – Frequently Asked Questions
1) What thread and size are the Metallics JSBH55 hex bolts?
They're 1/4-20 UNC hex bolts, 4 inches long. Thread pitch is 20 threads per inch and the shank measures 0.2450 to 0.2500 inch outside diameter, so they take a standard 1/4-20 nut or a tapped 1/4-20 hole.
2) Are these stainless bolts okay for outdoor or washdown use?
The JSBH55 is 18-8 stainless steel, which handles general atmospheric corrosion, and it's commonly used on chemical and food-processing equipment. Harsher chemical exposure can call for 316 stainless or other special corrosion-resistant materials instead.
3) What size wrench or socket fits these 1/4-20 stainless hex bolts?
Across the flats the hex head measures 0.428 to 0.438 inch, which is a 7/16 inch wrench or socket. Head height runs 0.150 to 0.163 inch.
4) How strong is a 1/4-20 18-8 stainless hex bolt like this one?
Tensile strength is 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness falls in the Rockwell B95 to C32 range. That's a corrosion-resistant austenitic fastener, not a hardened high-strength grade like an SAE Grade 8, so don't substitute it where a graded alloy bolt is specified.
5) How many bolts come in a jar of Metallics JSBH55, and can I buy less?
They ship as a jar of 100 pieces, and 100 count is the order minimum, so the jar is the smallest unit. Other sizes and quantities are available by request.
6) Do these come with nuts and washers?
No. The JSBH55 is bolts only, 100 hex bolts to the jar. Order 1/4-20 nuts and 1/4 inch washers separately, and match them in 18-8 stainless if you want to avoid galvanic issues with the bolt.
7) Do these Metallics hex bolts meet Buy American and ARRA requirements for a public job?
The JSBH55 is flagged compliant for both Buy American and ARRA in the manufacturer data, though country of origin is listed as China. On federally funded work, verify the compliance basis against your specific contract clause before you submit it.
8) Will a 4 inch long 1/4-20 bolt be long enough for my assembly?
The JSBH55 gives you 4 inches of bolt under the head, so figure your total stack-up (material thickness plus washers plus nut height) against that. For thinner assemblies the extra length just leaves you with protruding thread; Metallics offers other lengths in this hex bolt line by request if you need shorter.
