Value Collection 526050PR M12x1.75 Hex Jam Nut Grade 2H Zinc

Product Description

The VALUE COLLECTION 526050PR is an M12 x 1.75 hex jam nut manufactured from Grade 2H steel with a zinc-plated finish. Jam nuts are thin hex nuts used primarily as locknuts to secure a standard nut against loosening or to adjust bearing preload. This fastener carries a right-hand thread and measures 19 mm across the flats and 6 mm in height. It conforms to DIN 439 and ISO 4035 dimensional standards. At 0.05 pounds per piece, it is suited for high-volume mechanical and structural assembly work where a low-profile locking nut is required.

This jam nut is used across a broad range of industrial, mechanical, and construction applications wherever an M12 x 1.75 thread pitch is specified. Typical applications include machinery assembly, structural steel connections, threaded rod installations, and equipment fabrication. The zinc plating provides a basic level of corrosion resistance for general indoor and sheltered outdoor environments. It is installed by maintenance technicians, millwrights, pipefitters, and general tradespeople working with metric fastener systems.

Key Features

• M12 x 1.75 right-hand thread for standard metric fastener systems
• Grade 2H steel construction for reliable mechanical strength
• Zinc-plated finish provides corrosion resistance in general service environments
• Low-profile jam nut design at 6 mm height — ideal for locknut applications
• Conforms to DIN 439 and ISO 4035 fastener standards
• 19 mm width across flats fits standard M12 hex tooling

Compatibility

Designed for use with any M12 x 1.75 metric threaded bolt, stud, or rod conforming to standard metric thread specifications per DIN and ISO fastener standards.

Installation Notes

Install with a standard 19 mm open-end, box-end, or socket wrench. When used as a locknut, thread the jam nut against the primary nut and hold the primary nut stationary while tightening the jam nut to create a friction lock. Power down or de-energize any associated equipment before performing fastener service on machinery or enclosures. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific joint being assembled.
