A manufacturer of plumbing fixtures was using 10-24 and 8-32 Slotted Round Head Nylon Patch Monel Machine Screws as bibb screws to assemble neoprene washers to brass faucet stems. The costly nylon patch machine screws were losing their locking torque after multiple cycling. Excess torque was required to tighten the neoprene washer to the faucet stem.


The manufacturer replaced the nylon patch machine screws with 10-24 x 7/16 Phillips #8 Round Head Brass POWERLOK. The neoprene washer was seated firmly at a seating torque averaging 18 lb. -inches. The breakaway torque averaged 14 lb. -inches.

Customer Benefit

POWERLOK screws repeatedly retain their locking action through multiple cycling and exceed IFI locking standards by as much as 400%. POWERLOK screws also have locking action over the entire length of the engaged shank and eliminated the costly nylon patch application in addition to improving overall product reliability.
