Value Collection 665 Serrated Flange Nut 1/4-20 Pack of 50

Product Description

The VALUE COLLECTION 665 is a serrated flange nut in a 1/4-20 thread size with a black finish. The integrated serrated flange distributes clamping load across a wider bearing surface and bites into the mating material to resist loosening under vibration. The flange diameter measures 11/16 inches and the across-flats dimension is 7/16 inches. These nuts are commonly installed by electricians, HVAC technicians, plumbers, and general trade contractors wherever a secure, vibration-resistant fastening point is needed on light structural or equipment assemblies.

Serrated flange nuts in 1/4-20 thread are widely used in residential and light commercial applications including equipment panel mounting, conduit support hardware, ductwork brackets, and general mechanical assemblies. The black finish provides a degree of corrosion resistance suitable for indoor and sheltered installations. This SKU ships in a pack of 50, making it practical for service vehicles and shop stock.
