Metallics JBSC14112 1/4-20 x 1-1/2 in. Socket Button Head Hex Cap Screws - Alloy Steel Black - Each

No. Metallics states plainly that these socket button head screws are not recommended for critical, high-strength applications. The button head has a shallower socket and less head bearing area than a standard socket head cap screw, so for a load-bearing joint step up to an alloy steel socket head cap screw or a graded hex bolt instead. Use these for covers, panels, brackets and other non-critical fastening.

4,430 lb minimum tensile load, with the screw heat treated to Rockwell C39-44. Metallics notes that tensile testing only applies to screws at least three diameters long, which a 1-1/2 inch 1/4-20 clears. Even with that rating, Metallics does not recommend these for critical high-strength use.

They take a hex key (Allen) drive, not a Phillips or Torx bit. Socket depth is 0.087 inches, so seat the key fully before applying torque. Button heads have a shallower socket than cap screws of the same size, which is why a worn or undersized hex key strips them easily.

They come in a jar, with a 100-count minimum order. That makes it a shop or truck-stock item rather than a loose single screw, which suits MRO crews restocking a bin of 1/4-20 fasteners.

Treat them as indoor, dry-location hardware. The JBSC14112 is alloy steel with a black finish and no corrosion-resistant plating called out, so for wet, exterior or washdown environments pick a stainless or hot-dip galvanized fastener instead.

The JBSC14112 is flagged compliant for both ARRA and Buy American in Metallics' product data, though country of origin is listed as China. On a federally funded project, verify which standard your contract invokes, since the two sets of requirements are not identical.
