C Washers are manufactured with an open slot for the inner diameter, allowing the washer to be slipped in and out of the joint with loosening the joint - not completely unbolting it. Used in applications where assembly and disassembly are needed. Machined from solid bar, these washers are very thick - ranging from 1/4" all the way up to 7/16" thick. Slots are cut oversize for easy on and off, and are available from #10 through 1-1/4" bolts and shafts. Popular in MRO, Machinery, power Generation, Power Transmission, and anywhere an extra strong washer/spacer is required. Turned and milled from 12L14 Low Carbon Steel Bar, material is DFARS compliant. Case Hardened for extra strength, and Black Oxide Plated for both appearance and improved corrosion resistance. 100% Made in the USA.

  • A Slotted inner diameter allows the washer to be assembled and disassembled without taking the joint completely apart
  • Machined out of solid steel - extra thick for strength and fit
  • Low Carbon Steel, Case Hardened, Black Oxide Plated
  • Used in MRO, Machinery, Transportation, where repairs or adjustments need to be made
