Value Collection HNI2025LH-100BX Hex Nut 1/4-20 Left Hand

Product Description

The VALUE COLLECTION HNI2025LH-100BX is a 1/4-20 hex nut with left-hand thread, manufactured from Grade 2 steel with a bright uncoated finish. It measures 7/16 inches across the flats and 7/32 inches in height. Left-hand thread fasteners turn counterclockwise to tighten, making them the correct choice in applications where standard right-hand nuts would loosen under rotational load. These nuts conform to the UNC thread standard and are installed by mechanics, millwrights, plumbers, and general tradespeople wherever left-hand thread fastener assemblies are required.

This hex nut is suited for maintenance, repair, and assembly work across mechanical, HVAC, plumbing, and industrial applications where left-hand thread fasteners are specified. Typical use cases include fan blade hubs, rotating shaft assemblies, and equipment where vibration or rotation would back off a standard right-hand nut. Sold in a minimum order quantity of 100 pieces, this part is appropriate for stocking in trade shops or service vehicles that regularly encounter left-hand thread hardware.

Key Features

• Left-hand thread direction prevents loosening in counterclockwise-rotating assemblies
• 1/4-20 UNC thread size for compatibility with standard 1/4-20 left-hand threaded fasteners
• Grade 2 steel construction provides adequate strength for general-duty mechanical applications
• Bright uncoated finish allows for easy visual inspection and thread gauging
• 7/16-inch across-flats dimension accepts standard 7/16-inch hex wrench or socket
• Sold in 100-piece minimum quantity for shop stock or bulk repair use

Compatibility

Designed for use with 1/4-20 UNC left-hand threaded bolts and studs in general mechanical and trade assembly applications.

Installation Notes

Left-hand thread nuts tighten by turning counterclockwise and loosen clockwise — confirm thread direction before installation to avoid cross-threading or damage. Use a 7/16-inch open-end wrench, box wrench, or socket to drive and seat the nut. Ensure mating bolt or stud is also left-hand thread before assembly. Follow applicable mechanical codes and torque guidelines specified by the equipment manufacturer for the fastener grade and size.
