Product Overview

Split lock washers can help to prevent nuts or bolts from loosening by adding a spring tension force along with split edges that are designed to dig into the nut and material being fastened. For additional loosening resistance, use a lock washer on the nut side as well as on the head side. Split lock washers may not be as effective on extremely hard metals as the edges at the split cannot dig in to the surface as well.
  • Size: 1/2 in.
  • Round washer with a split and helical shape
  • When fully fastened, the edges at the split bite into the nut and material surface
  • Provides a spring tension force that adds additional friction
  • Helps to prevent nuts from loosening in cases where it may be subject to vibration, in some applications a flat washer is used with the split lock washer
  • Specification(s) met: ASME B18.21.1 and SAE J403

These lock washers sucked. They were slightly undersized and had to be hammered onto the bolt shafts. Packaging indicated correct size of half inch. I have never experienced this issue before in my entire life. I speculate size was tweaked down to save material in manufacturing to reduce cost. We were in the middle of a job and did not have the luxury of return or exchange.
