Value Collection 42941 Set Screw M8 X 1.25 Grade 14.9 25-pack

Product Description

The VALUE COLLECTION 42941 is an M8 x 1.25 x 14 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H). This fastener is designed for high-load holding and locking applications where a concealed, flush-drive solution is required. The cup point geometry bites into the mating surface to resist rotation and axial movement under vibration or heavy loads. Drive is via a 4 mm hex key. The DIN 916 standard governs the dimensional and mechanical requirements. Machinists, millwrights, and industrial maintenance technicians are the primary installers. Each package contains 25 pieces.

This set screw is suited for mechanical assemblies where shaft-to-hub connections, collars, pulleys, gears, or similar components must be locked in position. The metric thread standard makes it compatible with metric-dimensioned shafts and tapped holes in manufacturing, machine tool, and general industrial maintenance environments. The Grade 14.9 (45H) rating indicates high tensile strength, making this appropriate for demanding clamping and retention tasks where lower-grade fasteners would fail or loosen over time.

Key Features

• M8 x 1.25 metric thread with 14 mm overall length
• Cup point geometry for firm surface bite and resistance to rotation and axial movement
• Alloy steel construction rated to Grade 14.9 (45H) for high tensile strength
• 4 mm hex key drive for easy installation in confined spaces
• Conforms to DIN 916 fastener standard
• Sold in a 25-piece package to support job-lot and maintenance stock needs

Compatibility

Designed for use in metric-tapped M8 x 1.25 holes in shaft collars, hubs, pulleys, gears, and similar mechanical components requiring a flush-drive locking fastener per DIN 916.

Installation Notes

Install and remove using a 4 mm hex key; ensure the key is fully seated before applying torque to avoid rounding the drive socket. De-energize and lock out all machinery before servicing any fastener on rotating or loaded assemblies in accordance with applicable OSHA lockout/tagout procedures. Verify that the mating tapped hole meets DIN 916 thread tolerances before installation. Inspect the cup point and thread condition for damage before reuse.
