Value Collection 42945 M8x1.25x30mm Cup Point Set Screw 25pk

Product Description

The VALUE COLLECTION 42945 is a cup point set screw designed for mechanical assemblies requiring a secure, non-permanent fastening solution without a protruding head. Threaded M8 x 1.25 with an overall length of 30 mm, this screw is manufactured from alloy steel to Grade 14.9 (45H), delivering high tensile strength suitable for demanding industrial and trade applications. The cup point geometry bites into the mating surface to resist rotation and axial movement. Drive is via a 4 mm hex key socket, conforming to DIN 916. This fastener is well-suited for machinists, millwrights, maintenance technicians, and industrial tradespeople working on shafts, collars, and mechanical linkages.

This set screw is applied in scenarios where a flush or recessed fastener is required, such as locking shaft collars, pulleys, gears, and positioning fixtures on rotating or stationary shafts. The metric thread standard and DIN 916 compliance make it a direct-fit option for equipment built to metric specifications. It is commonly used in HVAC equipment assemblies, industrial machinery, pump drives, and mechanical power transmission components. Each package contains 25 pieces, allowing stocking of a working supply for shop or field use.

Key Features

• Cup point geometry creates positive bite on shaft surfaces to resist slippage under load
• Grade 14.9 (45H) alloy steel construction provides high tensile and torsional strength
• M8 x 1.25 metric thread with 30 mm overall length for deep engagement in threaded bores
• DIN 916 standard compliance ensures dimensional consistency and interchangeability
• 4 mm hex key drive allows installation in tight or recessed locations
• Sold in a 25-piece pack, suitable for shop stocking or multi-unit service jobs

Compatibility

Designed as a DIN 916-compliant metric set screw for use in any M8 x 1.25 threaded bore requiring a cup point, headless fastener.

Installation Notes

Installation is performed by threading technicians, machinists, or maintenance tradespeople using a 4 mm hex key or Allen driver. Ensure the mating threaded bore is clean and free of debris before installation. Apply appropriate thread-locking compound if vibration loosening is a concern in the specific application. Do not exceed the rated torque specification published by the equipment manufacturer for M8 Grade 14.9 fasteners.
