Value Collection 330350PS 1/4-28 Unf Grade 2 Zinc Jam Nut

Product Description

The VALUE COLLECTION 330350PS is a 1/4-28 UNF jam nut manufactured from Grade 2 steel with a zinc-plated finish. Jam nuts are thin hex nuts used to lock a standard nut in place or to secure a fastener in a fixed position against vibration or movement. This nut features right-hand threading and measures 7/16 inches across the flats with a height of 0.1563 inches. The zinc coating provides basic corrosion resistance suitable for general indoor and light-duty outdoor applications. Installation requires a standard 7/16-inch wrench or socket. Sold individually, with a minimum order quantity of 100 units.

This jam nut is suited for general mechanical assembly, HVAC equipment panels, electrical enclosures, plumbing fixture mounting, and similar light-to-medium fastening applications where a low-profile locking nut is required. The 1/4-28 UNF fine thread provides tighter thread engagement compared to coarse-thread equivalents, making it a common choice in vibration-prone assemblies and precision hardware applications across trade industries.

Key Features

• 1/4-28 UNF fine thread for tighter engagement in vibration-prone assemblies
• Grade 2 steel construction for general-purpose mechanical applications
• Zinc-plated finish for basic corrosion resistance
• Low-profile jam nut design at 0.1563 inches tall for space-constrained installations
• Right-hand thread direction, standard orientation
• 7/16-inch across-flats dimension compatible with standard hex wrenches and sockets

Compatibility

Designed as a standard 1/4-28 UNF jam nut suitable for general-purpose fastening applications requiring a Grade 2 steel, zinc-plated low-profile hex nut.

Installation Notes

Install and tighten with a 7/16-inch wrench or socket. Jam nuts are typically threaded on first, followed by a standard nut that is torqued down and then back-tightened against the jam nut to create a locking pair. Ensure mating threads are clean and free of debris before installation. Do not use in applications requiring military-specification fasteners.
