Metallics JSHC342 – Frequently Asked Questions
1) What thread does the Metallics JSHC342 socket head cap screw take, and will it thread into a standard 3/4-10 tapped hole?
It's a 3/4-10 UN thread, 10 threads per inch, so it mates with any standard 3/4-10 UNC tapped hole or nut. Shank length is 2 inches under the head.
2) How big a counterbore do I need for this 3/4 in. socket head cap screw?
Head width runs 1.107 to 1.125 inches and head height 0.74 to 0.75 inches, so plan a counterbore just over 1-1/8 inches across and at least 3/4 inch deep if you want the head flush or below the surface. Head geometry follows ASME B18.3-2012.
3) Is a socket head cap screw stronger than a Grade 8 hex bolt of the same size?
The alloy steel socket head version carries 170,000 psi minimum tensile and 162,000 psi minimum yield, higher than equivalent sizes of Grade 5 or Grade 8 hex head cap screws, and because it's internally wrenched it needs less surface area or clearance around the head. Hardness is Rockwell C39. If you have wrench clearance and only need Grade 5 or 8 strength, a hex head bolt is the cheaper route; pick the socket head when the head has to sit in a counterbore or in tight quarters.
4) Do these Metallics cap screws meet Buy American or ARRA requirements for a government job?
No. The JSHC342 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic-content requirements you'll need a domestically sourced fastener instead.
5) Is the black finish on these alloy steel cap screws suitable for outdoor or wet locations?
The JSHC342 is alloy steel with a plain black finish, which is an indoor, dry-location fastener. It has no corrosion-resistant plating, so for exterior, damp, or washdown work use a zinc-plated or stainless cap screw instead.
6) How are these 3/4-10 x 2 in. socket head cap screws packaged, and is there a minimum order?
They ship in a jar, with a 25 each minimum order. Total jar weight is 3.1 lbs.
7) Has this length of socket head cap screw been tensile tested?
Yes. At 2 inches long on a 3/4 inch nominal diameter this screw exceeds 3D, and cap screws of 3D length or greater are subject to tensile strength, yield strength, elongation, and reduction of area testing. Elongation is 10% minimum and reduction of area 33% minimum on machined specimens.
8) What trades use a 3/4-10 socket head cap screw like this?
Metallics lists the SHC series for electrical, plumbing, and heating and air conditioning work. Typical uses are anchoring equipment bases, pipe and duct supports, motor and pump mounts, and anywhere a high-strength bolt has to sit in a counterbore.
9) Can I get this socket head cap screw in a different length or diameter?
Yes. Metallics lists other sizes and quantities in the SHC socket head cap screw line available by request; the JSHC342 is the 3/4-10 x 2 inch alloy steel black configuration.
