#10 Combination Internal/External Tooth Lock Washers, Steel, Zinc, Pack of 100

These #10 combination internal/external tooth lock washers are for buyers securing nuts or bolt heads in fastening assemblies. Their dual-tooth design helps resist backoff rotation while providing a secure bearing surface.

Made of steel with a zinc finish, these washers combine internal and external teeth. The internal teeth engage bolt heads or nuts and are suited to smaller-head screws, including fillister heads. External teeth increase the bearing area and allow the nut or bolt to be rotated without distorting the bearing surface. Pack includes 100 washers.

Key Features:

• Combination tooth design: Provides internal and external tooth engagement in one lock washer.
• Internal teeth: Help resist backoff rotation at the bolt head or nut.
• External teeth: Increase the bearing area and help maintain the bearing surface during rotation.
• #10 size: Fits #10 fastening applications.
• 100-piece pack: Supplies multiple washers for stocking or assembly work.

Choose these #10 steel, zinc-finished combination tooth lock washers when fastening work calls for both internal and external tooth engagement. The 100-piece pack supports recurring hardware needs.
