Value Collection A996274 Left Hand Hex Jam Nut 1-14 Unf

Product Description

The VALUE COLLECTION A996274 is a left-hand thread hex jam nut designed for applications where standard right-hand fasteners are not suitable. Manufactured from steel with a zinc clear finish, this nut measures 1.5 inches across the flats and 0.5469 inches in height. The 1-14 UNF thread specification indicates a 1-inch nominal diameter with 14 threads per inch, a fine-thread pitch commonly used in precision assemblies and mechanical systems requiring controlled clamping force. Licensed tradespeople and maintenance technicians working on threaded rod assemblies, locknuts, or counter-rotation fastening applications will find this nut appropriate for their work.

This hex jam nut is suited for mechanical, industrial, and trade-service applications where left-hand threading is required to resist loosening caused by rotational forces. Typical installation scenarios include pump shafts, motor spindles, fan assemblies, and other rotating equipment where vibration or counter-clockwise motion would back off a standard right-hand nut. The zinc clear finish provides a basic level of corrosion resistance appropriate for indoor or protected environments.

Key Features

• Left-hand UNF thread direction resists loosening in counter-clockwise rotating assemblies
• 1-14 UNF thread form for fine-pitch, precision fastening applications
• Steel construction provides reliable mechanical strength
• Zinc clear finish offers basic corrosion resistance
• Hex drive profile accepts standard open-end, box, or socket wrenches
• Jam nut profile allows use as a locking nut against a primary fastener

Compatibility

Designed as a replacement or service fastener for any threaded assembly using a 1-14 UNF left-hand thread specification. Verify thread direction and pitch before installation, as left-hand nuts are not interchangeable with standard right-hand hardware.

Installation Notes

This fastener should be installed by qualified mechanical or trade personnel familiar with left-hand thread conventions. Left-hand nuts tighten counter-clockwise and loosen clockwise, opposite of standard fasteners. Always de-energize and lock out rotating equipment before servicing threaded fasteners on shafts or spindles. Use appropriately sized open-end or box wrenches to avoid rounding the hex flats.
