NUT - SPECIAL (Clark CL3737221)

A damaged special nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, this aftermarket replacement part serves as a threaded fastener that mates with a bolt or stud to clamp components together. The catalog reference is Clark part number CL3737221. A common failure consequence for this type of fastener is gradual backing off, which may cause misalignment or detachment of the connected parts. Keeping a special nut in sound condition helps maintain consistent clamping force in applications where standard nuts may not suffice. This item ships at approximately 0.15 pounds.
