Value Collection 1/2-13 AJ6MC Brass Hex Jam Nut Nickel Plated

Product Description

The VALUE COLLECTION 1/2-13 AJ6MC is a self sealing hex jam nut machined from brass with a nickel plated finish. It features a 1/2-13 UNC right-hand thread and measures 3/4 inches wide by 7/32 inches high. A silicone O-ring with a 1/32-inch seal thickness is integrated into the nut to provide a positive fluid or pressure seal at the fastening point. This hardware is used in plumbing, fluid system, and mechanical assemblies where a standard jam nut must also resist leakage at the threaded connection. Installation is performed by plumbers, pipefitters, and mechanical technicians.

This nut is suited for applications where a low-profile locking and sealing fastener is required on a 1/2-13 UNC threaded stud or pipe fitting. Common install scenarios include fluid control panels, manifold assemblies, and equipment fittings in both residential and light commercial service environments. The nickel plating provides corrosion resistance in wet or humid conditions. Sold in a package quantity of five, making it appropriate for service calls requiring multiple replacements or new installations at a single site.

Key Features

• 1/2-13 UNC right-hand thread for standard compatibility with inch-series fastener systems
• Integrated silicone O-ring provides a positive seal at the threaded joint
• 1/32-inch O-ring seal thickness for consistent compression across the sealing surface
• Brass base material with nickel plating for corrosion resistance in wet environments
• Hex jam nut profile allows installation with standard open-end or box wrenches
• Package quantity of five units per order

Compatibility

Designed as a direct-fit self sealing hex jam nut for 1/2-13 UNC threaded connections in plumbing, fluid handling, and mechanical fastener applications requiring an integrated O-ring seal.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and de-energize any fluid or pneumatic system before removing or installing fasteners at a pressurized joint. Use an appropriately sized hex wrench or open-end wrench on the hex flats; avoid pipe wrenches or adjustable pliers that may damage the nickel plating or deform the hex profile. Verify that the silicone O-ring is properly seated before torquing the nut to the joint.
