Metallics JSHC51658 – Frequently Asked Questions

1) How does a 5/16-18 socket head cap screw compare to a Grade 5 or Grade 8 hex head bolt of the same size?
The Metallics JSHC51658 socket head cap screw is rated at 180,000 psi minimum tensile and 162,000 psi minimum yield, which is higher than equivalent sizes of Grade 5 or Grade 8 hex head cap screws. Because it is internally wrenched with a hex key rather than turned by a wrench on the outside of the head, it also needs less surface area or counterbore clearance around the head. That combination is why it gets specified where a hex head would not fit the pocket.
2) Is 5/16-18 a coarse thread, and will it thread into a standard 5/16 coarse tapped hole?
Yes. The screw is 18 threads per inch in the UN thread series, which is 5/16-18 UNC, the standard coarse pitch for 5/16 inch. It threads into any 5/16-18 tapped hole or nut.
3) Are these Metallics cap screws Buy American or ARRA compliant for a government or institutional job?
No. The JSHC51658 socket head cap screw is not Buy American compliant and is not ARRA compliant, and it is sourced from multiple countries of origin. If your contract carries a domestic-content clause, this item will not satisfy it.
4) Is the black finish on these alloy steel socket screws suitable for outdoor or wet locations?
These are alloy steel with a black finish, which is a plain oxide-type appearance, not a corrosion-resistant plating. Keep them to dry indoor or enclosed work, such as the electrical, plumbing, and HVAC applications they are catalogued for. For exposed or damp locations, go with a zinc plated or stainless socket head cap screw in the same 5/16-18 size instead.
5) Do I have to buy the Metallics JSHC51658 socket head cap screws in bulk, or can I order a few?
They ship as a jar of 100, and the order minimum is one jar. There is no loose-piece count on this item, so the smallest buy is the 100 piece jar.
6) How ductile is this alloy steel socket screw if the joint moves?
Elongation is 10 percent minimum and reduction of area 33 percent minimum on machined specimens, with hardness at Rockwell C39. That is a hard, high-strength fastener, so it carries load well but it is not meant to stretch and forgive misalignment. Pull up the joint square and torque to the engineer's value.
