Value Collection 831118PR Set Screw M8x1.25x35mm Cone Point

Product Description

The VALUE COLLECTION 831118PR is a metric set screw designed for mechanical assemblies requiring a secure, positive lock against rotational or axial movement. It features a cone point tip that bites into mating material for a firm hold and is driven with a 4 mm hex key. Manufactured from alloy steel to Grade 14.9 (45H), this fastener delivers high tensile and proof-load strength suitable for demanding industrial and mechanical applications. A black oxide finish provides mild corrosion resistance and reduces light reflection in service environments. Thread size is M8 x 1.25 with an overall length of 35 mm.

This set screw is used in shaft-to-hub connections, collars, pulleys, gears, and similar mechanical components where a headless fastener is required to sit flush or below the surface. It is appropriate for both light-duty and heavy-duty industrial assemblies. Trades and technicians working in manufacturing, maintenance, and mechanical installation environments will encounter this fastener in motor shaft collars, conveyor components, and precision machine fixtures. The cone point style is preferred where a permanent or semi-permanent bite into the mating shaft is acceptable.

Key Features

• Grade 14.9 (45H) alloy steel construction for high proof load and tensile strength
• Cone point tip provides aggressive bite into mating shaft or surface
• M8 x 1.25 metric thread with 35 mm overall length
• 4 mm hex key drive for installation with standard Allen wrenches
• Black oxide finish for mild corrosion resistance
• Conforms to DIN 914 and ISO 4027 fastener standards

Compatibility

Designed as a standard metric set screw conforming to DIN 914 and ISO 4027 for use in any M8 x 1.25 threaded bore requiring a cone point, headless fastener.

Installation Notes

Installation is performed with a 4 mm hex key torqued to the assembly specification for Grade 14.9 fasteners. Ensure the threaded bore is clean and free of debris before installation. The cone point will indent the mating shaft upon full engagement, so confirm permanent or semi-permanent fastening is acceptable for the application before tightening. Follow applicable machinery safety lockout and tagout procedures before servicing any assembly that contains this fastener.
