Value Collection 330190BR Hex Jam Nut 3/4-10 Unc Grade 2

Product Description

The VALUE COLLECTION 330190BR is a 3/4-10 UNC hex jam nut manufactured from Grade 2 steel with a zinc-plated finish. Jam nuts are intentionally thin fasteners used to lock a standard nut in place or to secure components where full nut height is not required. This nut features a right-hand thread, measures 1-1/8 inches across the flats, and has a height of 0.4219 inches. The zinc coating provides basic corrosion resistance for general indoor and light outdoor applications. Trade professionals and maintenance technicians use these nuts in mechanical assemblies, equipment mounting, and fastener locknut configurations across a broad range of maintenance and construction tasks.

This jam nut is suited for use in general mechanical, construction, HVAC equipment mounting, plumbing support structures, and electrical panel or enclosure assemblies where a 3/4-10 UNC thread pattern is specified. The Grade 2 steel rating indicates this is a general-purpose fastener appropriate for low-to-moderate load applications. It is not rated for high-strength structural connections or applications requiring military specification fasteners. Sold individually, with a minimum order quantity of 50 pieces per order.

Key Features

• 3/4-10 UNC right-hand thread for standard inch-series fastener applications
• Jam nut profile at 0.4219 inches tall for locknut and space-constrained uses
• 1-1/8 inches across the flats for standard 3/4-10 wrench fitment
• Grade 2 steel construction for general-purpose low-to-moderate load service
• Zinc-plated finish for basic corrosion resistance
• Does not meet military specifications — for commercial use only

Compatibility

Designed for use in any assembly specifying a 3/4-10 UNC right-hand thread hex jam nut in Grade 2 steel. Suitable as a general-purpose replacement or new-installation fastener in mechanical, HVAC, plumbing, and electrical support applications.

Installation Notes

Install using a standard open-end or box wrench sized for 1-1/8 inches across the flats. When used as a locknut, thread the jam nut against a standard nut and hold the jam nut while tightening the primary nut to create the locking effect. Do not use Grade 2 fasteners as substitutes for high-strength or structural-grade hardware in load-bearing connections. No special tools or certifications are required for standard mechanical assembly use.
