Value Collection 533114P M8 X 1.25 X 25 Mm Cup Point Set Screw

Product Description

The VALUE COLLECTION 533114P is an M8 x 1.25 x 25 mm cup point set screw designed for secure, headless fastening in mechanical assemblies. It is manufactured from alloy steel to Grade 14.9 (45H), which provides high tensile and proof load strength suited to demanding clamping and locking applications. The cup point geometry bites into the mating surface to resist rotation and axial movement. Drive engagement is achieved with a 4 mm hex key. This fastener conforms to DIN 916 standards and is appropriate for use by maintenance technicians, machine builders, and industrial assembly professionals.

This set screw is used in shaft-to-hub assemblies, collar positioning, and mechanical stop applications across general industrial, HVAC equipment, and rotating machinery installations. The metric M8 x 1.25 thread pitch and 25 mm overall length make it a common choice for mid-size mechanical components where a flush or recessed fastener is required. It is sold individually but must be ordered in multiples of 100 units.

Key Features

• Grade 14.9 (45H) alloy steel construction for high clamping strength
• Cup point geometry resists rotation and axial movement on mating surfaces
• DIN 916 standard compliance ensures dimensional consistency
• 4 mm hex drive for precise torque application with a standard hex key
• Metric M8 x 1.25 thread for compatibility with standard metric tapped holes
• Headless design allows fully recessed installation flush with or below the surface

Compatibility

Designed as a DIN 916-compliant metric set screw for use in any M8 x 1.25 tapped hole application requiring a cup point, headless fastener in alloy steel.

Installation Notes

Installation requires a 4 mm hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any associated equipment before servicing assemblies containing set screws. Do not exceed the rated grade strength by applying impact or improvised drive tools that could strip the hex socket.
