Value Collection 34294 Serrated Flange Nut 3/8-16 Grade 2 Zinc

Product Description

The VALUE COLLECTION 34294 is a 3/8-16 serrated flange nut manufactured from Grade 2 steel with a zinc-plated finish. The integrated serrated flange distributes clamping load over a wider bearing surface and bites into the mating material to resist loosening under vibration. The flange diameter measures 0.75 inches and the overall height reaches 0.347 inches. This fastener suits general mechanical assembly work in HVAC equipment, electrical enclosures, plumbing fixture mounting, and structural bracketing applications where a separate lock washer is undesirable. Installation is performed by any trade technician working with standard threaded 3/8-16 fastener hardware.

This nut is suited for light to medium-duty inch-series assembly applications. The zinc coating provides baseline corrosion resistance for indoor and sheltered outdoor environments. The serrated flange eliminates the need for a separate star or split lock washer, reducing component count on the assembly. Typical uses include mounting brackets, equipment panels, conduit supports, and similar structural connections in residential and light commercial trade work.

Key Features

• Serrated flange eliminates need for a separate lock washer
• Grade 2 steel construction for general-purpose mechanical fastening
• Zinc-plated finish for baseline corrosion resistance
• 3/8-16 UNC thread for compatibility with standard inch-series hardware
• Flange diameter of 0.75 inches distributes clamping load over a wider surface area
• Width across flats between 0.551 and 0.562 inches fits standard 9/16-inch wrenching

Compatibility

Designed as a standard inch-series replacement or stock fastener for any 3/8-16 threaded assembly requiring a serrated flange nut in Grade 2 steel.

Installation Notes

Install using a 9/16-inch wrench or socket driver. Ensure the serrated flange face seats flush against the mating surface to allow the serrations to engage properly. Do not install with an additional washer between the flange and the work surface, as this defeats the anti-loosening function of the serrations.
