Value Collection 526042PS Hex Jam Nut M8 X 1.25 Zinc-plated

Product Description

The VALUE COLLECTION 526042PS is a metric hex jam nut designed for low-profile fastening applications where space between mating surfaces is limited. Manufactured from Grade 2H steel with a zinc-plated finish, this nut meets DIN 439 and ISO 4035 standards. It carries an M8 x 1.25 thread size with a right-hand thread direction and measures 13 millimeters across flats and 4 millimeters in height. The zinc coating provides basic corrosion resistance for general industrial and mechanical assembly use. Machinists, maintenance technicians, and assembly professionals typically install these as locking elements against a primary nut or in tight-clearance fastening situations.

This jam nut is suited for general-purpose mechanical assemblies where a thin, low-profile nut is required to lock or retain a primary fastener. Typical applications include equipment fabrication, machinery maintenance, and structural assemblies that call for metric hardware conforming to DIN 439 or ISO 4035 specifications. The zinc-plated finish makes it appropriate for indoor or lightly protected environments. Minimum order quantity is 100 pieces; each package contains 1 nut.

Key Features

• M8 x 1.25 right-hand thread for standard metric fastener compatibility
• Grade 2H steel construction conforming to DIN 439 and ISO 4035 standards
• Zinc-plated finish for basic corrosion resistance
• Low-profile jam nut design at 4 millimeters height for tight-clearance applications
• 13 millimeters across flats, 14.38 millimeters across points

Compatibility

Designed as a standard metric jam nut for use with M8 x 1.25 threaded fasteners and hardware conforming to DIN 439 and ISO 4035 dimensional standards.

Installation Notes

Installation is performed with a standard 13 millimeter open-end, box-end, or socket wrench. Always de-energize and lock out any machinery before accessing fastener locations on live equipment. When used as a locking nut, thread the jam nut onto the bolt first, then install the primary nut and tighten both against each other. Do not reuse deformed or cross-threaded nuts.
