Metallics SRM136 – Frequently Asked Questions
1) What thread size and pitch are the Metallics SRM136 machine screws, and will they take a standard 1/4-20 nut?
The SRM136 is a 1/4-20 screw: 1/4 inch nominal diameter at 20 threads per inch, which is the standard UNC coarse pitch for that diameter. Any standard 1/4-20 nut or tapped 1/4-20 hole will accept it. Overall length is 6 inches.
2) Are the Metallics SRM136 screws stainless, and can they be used outdoors or in damp locations?
They are 18-8 stainless steel, the austenitic 300-series grade used for general corrosion resistance. That makes them suitable for damp and exposed work where plated carbon steel would rust, such as outdoor junction boxes, strut, and mechanical rooms.
3) Are the Metallics SRM136 screws Buy American or ARRA compliant for a government job?
No. The SRM136 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded project with domestic sourcing requirements, this screw will not satisfy them.
4) What tensile strength can I count on from these stainless machine screws?
Rated at 80,000 psi minimum tensile, with a hardness of Rockwell B85 to B95. One caution worth knowing: there is no single performance standard for stainless machine screws, so stainless tensile figures are approximations rather than a graded guarantee. If your drawing calls out a specific bolt grade with a verified proof load, a graded carbon steel fastener is the correct specification instead.
5) Will the SRM136 thread into sheet metal or wood?
No. It is a machine screw with a uniform 20 TPI machine thread and a blunt end, so it needs a nut or a tapped hole. For sheet metal use a self-tapping or thread-cutting screw; for wood use a wood screw or a lag.
6) What trades actually use these round head slotted machine screws?
Metallics lists the SRM136 for the electrical, plumbing, and heating and air conditioning trades. In practice that is panel and enclosure hardware, strut and hanger assemblies, duct and equipment mounting, anywhere a machine thread into a nut or tapped plate beats a sheet metal screw.
