Value Collection 329170BR Hex Jam Nut 5/8-11 Grade 2

Product Description

The VALUE COLLECTION 329170BR is a 5/8-11 hex jam nut made from Grade 2 steel with a bright, uncoated finish. Jam nuts are low-profile hex nuts used to lock a standard nut in place or serve as a fastener where reduced stack height is required. This nut features right-hand UNC threading, measures 5/16 inches across the flats, and stands 3/8 inches tall. At 0.05 pounds, it is a lightweight hardware component suited for general-purpose mechanical and structural fastening applications. Licensed trades and maintenance technicians rely on this type of fastener for equipment assembly, pipe support bracketing, and equipment mounting tasks.

This jam nut is suited for residential and commercial maintenance, equipment fabrication, and general mechanical assembly where a 5/8-11 UNC thread pattern is specified. Its uncoated finish makes it appropriate for dry, indoor environments or applications where a secondary coating or plating will be applied after installation. HVAC technicians, plumbers, and electricians commonly encounter this fastener when securing equipment supports, unistrut hardware, or structural brackets.

Key Features

• 5/8-11 UNC right-hand thread for standard American fastener compatibility
• Grade 2 steel construction provides adequate strength for general-purpose use
• Bright, uncoated finish for applications where coating is not required
• Low-profile jam nut design at 3/8 inches tall for tight-clearance installations
• 5/16 inches across the flats for use with standard hex wrenches and sockets

Compatibility

Designed as a general-purpose replacement or stocking fastener for any application requiring a 5/8-11 UNC hex jam nut in Grade 2 steel.

Installation Notes

Installation requires a standard hex wrench or socket sized to the flat width. Always hand-thread the nut fully before applying tool torque to avoid cross-threading. When using as a jam nut, snug the primary nut to position first, then tighten the jam nut against it while holding the primary nut stationary. Follow applicable mechanical or structural codes for fastener torque requirements based on the specific assembly.
