Milwaukee M5 x 0.8 Countersunk Washer Head Hex Socket Screw
Model Number: 05-74-0021
The Milwaukee 05-74-0021 is a genuine OEM M5 x 0.8-6g Countersunk Washer Head (CWH) Hex Socket Screw for use in compatible Milwaukee tools. The countersunk washer head profile combines a tapered countersunk bearing surface with an integrated washer face — allowing the screw to seat flush or below the surface of a countersunk hole while distributing clamping load over a larger bearing area than a standard flathead screw. The internal hex socket recess (Type B) is driven with an Allen key or hex bit, providing controlled torque and high clamping force in a low- profile installation. The M5 x 0.8 mm thread and 6g tolerance class ensure precise thread engagement with the mating nut or tapped hole. A stripped, corroded, or missing screw that can no longer hold its fastened joint securely requires replacement to restore proper assembly integrity and safe tool operation.
Using a genuine Milwaukee OEM screw ensures the correct M5 x 0.8 thread pitch, 6g thread tolerance, countersunk washer head geometry, and hex socket drive specification for the fastener interface it serves. Non-OEM screws may not match the original thread class or head geometry, leading to improper seating in the countersunk surface or insufficient clamping force at the joint. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct screw for your specific unit.
