Value Collection 831116PR M8 Set Screw Cone Point Alloy Steel

Product Description

The VALUE COLLECTION 831116PR is an M8 x 1.25 x 30 mm cone point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a hex drive socket sized at 4 mm and a black oxide finish that provides basic corrosion resistance for indoor and protected environments. This fastener is fully metric and conforms to DIN 914 and ISO 4027 standards. Cone point set screws are used where a positive, semi-permanent locking bite into a mating surface is required. Licensed trades and industrial maintenance technicians install these where shaft-to-hub or collar-to-shaft locking is critical under vibration or rotational load.

This set screw is suited for mechanical assembly, power transmission components, shaft collars, gears, couplings, and similar applications where a metric M8 threaded hole and a 30 mm overall engagement length are specified. The cone point geometry concentrates clamping force to a single contact area, making it effective for locking onto hardened or case-hardened shaft surfaces. It is appropriate for both light industrial and OEM assembly contexts where DIN or ISO fastener standards are called out on engineering drawings.

Key Features

• M8 x 1.25 thread form, 30 mm overall length, fully metric dimensioning per DIN 914 and ISO 4027
• Cone point geometry provides concentrated locking engagement on shaft or mating surface
• Alloy steel construction at Grade 14.9 (45H) for high tensile and torsional strength
• 4 mm hex key drive for precise torque application with standard metric hex wrenches
• Black oxide finish for surface protection in dry or lightly oiled service environments

Compatibility

Designed as a standard metric set screw for any M8 x 1.25 tapped hole application requiring cone point engagement per DIN 914 or ISO 4027 specifications.

Installation Notes

Installation is performed with a 4 mm metric hex key. Ensure the mating threaded hole is clean and free of debris before driving the screw. Apply appropriate thread-locking compound if vibration resistance is required beyond the cone point contact alone. Do not exceed the torque specification called out on the relevant engineering drawing for Grade 14.9 fasteners in the given base material.
