Metallics JFM131 – Frequently Asked Questions
1) How much load will a 1/4-20 zinc plated steel machine screw hold?
The JFM131 carries a 1900 lb minimum tensile strength, with hardness in the Rockwell B70 to B100 range and steel made to AISI 1006 - 1022. That is a low carbon commercial fastener, fine for mounting panels, device plates, enclosures and brackets. It is not a graded structural bolt, so for structural or high-torque connections step up to a Grade 5 or Grade 8 hex bolt instead.
2) Can these zinc plated screws be used outdoors or in a damp location?
The finish is zinc plating over steel, which handles indoor and dry-location work and resists incidental moisture. Zinc plate is a sacrificial coating, not a corrosion-proof one, so for exterior, wash-down or coastal exposure specify 18-8 stainless or hot dip galvanized instead. Note that hardness and tensile figures for stainless machine screws are guides only, since no national standard sets those performance requirements.
3) Do these Metallics machine screws meet Buy American or ARRA requirements for a government job?
The JFM131 is flagged compliant for both ARRA and Buy American, though country of origin is listed as China. On federally funded work where a domestic-melt or domestic-manufacture clause applies, verify the specific clause in your contract against those flags before submitting.
4) How are the Metallics JFM131 screws packaged and what is the minimum order?
They come in a jar, with a 100 count minimum order. Jar packaging suits a service van or a shop bench bin where a loose box would spill.
