Value Collection 42923 M5 Set Screw Cup Point Alloy Steel Din 916 50pk

Product Description

The VALUE COLLECTION 42923 is an M5 x 0.80 x 14 mm cup point set screw made from alloy steel to Grade 14.9 (45H). Set screws are headless fasteners used to secure a component — such as a collar, gear, pulley, or sprocket — against or onto a shaft by applying direct clamping force through the point. The cup point geometry bites into the mating surface for strong holding power without a through-hole. The hex drive (2.50 mm hex key) allows installation in tight clearance areas where a standard hex head bolt cannot fit. Machinists, millwrights, and maintenance technicians install these in both production and field environments.

These set screws are suited for mechanical assembly applications across industrial, HVAC equipment, and general trade environments. The metric M5 x 0.80 thread and DIN 916 standard make them a direct fit for equipment designed to metric fastener specifications. The 14 mm overall length provides adequate thread engagement for M5 boss depths common in light to medium-duty machine components. Sold in a pack of 50, this quantity suits both job-site stock and shop inventory replenishment.

Key Features

• M5 x 0.80 metric thread with 14 mm overall length for consistent thread engagement
• Cup point geometry bites into shaft surface for reliable anti-rotation holding force
• Alloy steel construction at Grade 14.9 (45H) delivers high tensile and torsional strength
• Hex socket drive requires a 2.50 mm hex key — fits confined installation spaces
• Conforms to DIN 916 fastener standard for dimensional consistency
• Pack of 50 supports inventory stocking and repeat-use applications

Compatibility

Designed as a standard DIN 916 metric set screw for any application requiring an M5 x 0.80 cup point fastener in alloy steel. Compatible with any component tapped to M5 x 0.80 metric thread specification.

Installation Notes

Install and remove using a 2.50 mm hex key; use a properly sized key to avoid rounding the socket. Ensure the mating threaded hole is clean and free of debris before installation. Apply appropriate thread-locking compound if vibration is a concern in the application. Always de-energize and lock out equipment before performing fastener service on rotating components.
