1/4-20 x 1 7/8 Alloy Steel Socket Head Cap Screw is an alloy steel socket head cap screw for repair work where a drawing calls for an odd length. It is useful for assembly equipment, guide rails, and machine housings, especially when the 1/4-20 thread and 1 7/8 in. length must match existing parts rather than a nearby standard size. The cylindrical socket head works with counterbored pockets where head diameter, head height, and key size have to be checked before ordering. The page supports exact-size searches, purchase review, and maintenance matching without unsupported claims.
