APPLICATION Grooved studs are commonly used for a variety of applications including fastening brackets, control arms, knobs, handles, instruction panels, and nameplates. DESCRIPTION Grooved studs have three parallel grooves spaced at 120 intervals around the diameter of the shank. Standard grooved studs are manufactured from low carbon steel and are zinc plated for corrosion resistance. FUNCTION Grooved studs function in the same manner as grooved pins. They provide the same positive holding features as grooved pins plus additional end loading resistance provided by the head of the stud. STANDARD STUDS Standard studs are manufactured to ASME B18.8.2 specifications. Standard stud sizes available are from #0 through #16 and lengths from 1/8" through 1/2" as shown in the table below. STANDARD GROOVED STUD SIZES APPLICATIONS T head cotter in chain. Linkage assembly. Spring anchor. Fastening knobs, handles, etc. Attaching nameplates, instruction panels.

Machine keys are most commonly used in this manner to lock shaft and hub assemblies together to transmit torque. DESCRIPTION The complete line of DRIV-LOK high quality parallel machine keys includes square and rectangular keys with chamfered, square cut, or rounded ends. Most square keys are available with 45 chamfers at both ends for easy insertion and elimination of damage to keyways in shafts and hubs. FUNCTION Machine keys are well suited to transmit torque because of the large cross-sectional area which is utilized. The torque is efficiently transmitted between the shaft and the hub through the machine key. STANDARD MACHINE KEYS Standard square machine keys are manufactured from low carbon steel and have either square cut or chamfered ends. Standard square machine keys are available in widths from 1/8" through 1/2" and lengths from 1/2" through 4 1/2" as shown in the table.
