Gibraltar 23040.0082 Unequal Double Threaded Stud M8x1.25

Product Description

The GIBRALTAR 23040.0082 is an unequal double threaded stud designed for fastening applications that require different thread engagement lengths on each end. Manufactured from alloy steel with a heat-treated steel finish and rated to material grade 10.9, this stud delivers high tensile strength for demanding mechanical assemblies. The overall length is 63 mm, with a long thread length of 40 mm, a short thread length of 11 mm, and an unthreaded shank length of 12 mm. The M8 x 1.25 thread size conforms to DIN 787 thread fit class standards. It weighs approximately 0.044 pounds per piece.

Unequal double threaded studs like the 23040.0082 are used in mechanical, industrial, and equipment assembly applications where one end threads into a tapped hole or housing and the opposite end accepts a nut or mating component. The unequal thread lengths allow for optimized engagement depth on the fixed end while leaving sufficient thread exposure on the free end. These fasteners are common in machine building, fixture assembly, and general industrial maintenance. Licensed mechanics and industrial assemblers are the primary installers.

Key Features

• M8 x 1.25 thread size with DIN 787 thread fit class for standardized compatibility
• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Heat-treated steel finish for enhanced hardness and wear resistance
• Unequal thread configuration: 40 mm long thread, 11 mm short thread, 12 mm unthreaded shank
• 63 mm overall length suits mid-range fastening depth requirements
• No flat on shank, maintaining a clean cylindrical profile

Compatibility

Designed as a standard DIN 787 class M8 x 1.25 double threaded stud suitable for use in tapped housings, machine frames, and industrial assemblies requiring metric fasteners at this thread specification.

Installation Notes

Installation should be performed by qualified mechanical or industrial assembly personnel. Use an appropriate stud driver or locking nut method when threading the short end into the base material to avoid damaging threads. Ensure the receiving tapped hole is clean and free of debris before installation. Torque to the specification required by the assembly design, referencing applicable industry fastener standards for grade 10.9 metric studs.
