Value Collection KP83307 Unequal Double Threaded Stud M8x1.25

Product Description

The VALUE COLLECTION KP83307 is an unequal double threaded stud designed for mechanical fastening applications where two different thread engagement lengths are required on a single fastener. Manufactured from carbon steel at material grade 8.8, this stud features an M8 x 1.25 thread profile with an overall length of 40 mm. The long thread end measures 22 mm, the short thread end measures 10 mm, and an unthreaded shank of 8 mm separates the two threaded sections. No flat is present on the shank. It is supplied uncoated and sold in packages of 25. Mechanical assemblers, maintenance technicians, and fabricators install this type of fastener where a stud must engage one component on each end at differing depths.

Unequal double threaded studs like the KP83307 are commonly used in machinery assembly, structural fabrication, and equipment maintenance scenarios where a threaded insert or tapped hole on one side requires a shorter engagement while the mating nut or component on the opposite side requires deeper thread engagement. The M8 x 1.25 coarse thread pitch suits a wide range of general mechanical and light industrial applications. The grade 8.8 carbon steel construction provides reliable tensile strength for standard-duty clamping and fastening tasks.

Key Features

• Unequal thread design: 22 mm long thread end and 10 mm short thread end on a single stud
• M8 x 1.25 thread size with standard coarse pitch
• Grade 8.8 carbon steel for reliable tensile and yield strength in general mechanical use
• Unthreaded shank of 8 mm separates the two threaded sections
• Uncoated finish — suitable for use as-is or with field-applied coatings
• Sold in a package of 25 units for shop stock and maintenance inventory

Compatibility

Designed as a standard M8 x 1.25 unequal double threaded stud suitable for use in general mechanical assemblies, fabrication, and maintenance applications requiring grade 8.8 carbon steel fasteners with this thread specification.

Installation Notes

Installation is performed by mechanical technicians or assemblers using appropriate thread engagement tools such as a stud driver or double-nut method. Ensure the tapped hole or threaded insert is clean and free of debris before installation. Apply thread-locking compound or anti-seize as required by the application and applicable maintenance standards. Do not exceed the torque limits associated with grade 8.8 M8 fasteners as specified by the equipment manufacturer.
