Value Collection 533056PR Set Screw M5x0.80x20mm Cup Point

Product Description

The VALUE COLLECTION 533056PR is a metric set screw designed for secure component fastening in mechanical assemblies. It features a cup point tip that bites into a shaft or mating surface to resist rotation and axial movement without the need for a through-hole. The M5 x 0.80 thread pitch and 20 mm overall length make it well-suited for medium-duty clamping applications. Driven by a 2.50 mm hex key, this fastener is manufactured to DIN 916 standards from alloy steel at Grade 14.9 (45H), providing high tensile strength for demanding service conditions. Installed by machinists, millwrights, and maintenance technicians across industrial and mechanical trade work.

This set screw is used in applications where a headless fastener is required to lock pulleys, gears, collars, knobs, or similar components onto shafts. The cup point geometry creates a positive bite into softer shaft materials, making it a standard choice in power transmission, motion control, and general machine assembly. It conforms to DIN 916, the widely recognized international standard for hexagon socket set screws with cup points, ensuring dimensional interchangeability with other DIN 916-compliant fasteners of the same size.

Key Features

• Cup point tip bites into shaft surface for positive locking without a through-hole
• Grade 14.9 (45H) alloy steel provides high tensile and torsional strength
• Conforms to DIN 916 for dimensional interchangeability with other metric set screws
• 2.50 mm hex key drive for installation in tight or recessed locations
• M5 x 0.80 metric thread with 20 mm overall length suits medium-duty shaft-locking applications

Compatibility

Designed as a DIN 916 metric set screw replacement or new-install fastener for M5 x 0.80 threaded applications requiring a cup point, headless profile in mechanical and industrial assemblies.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 2.50 mm hex key. Power down and de-energize all rotating machinery before installing or removing set screws from shaft-mounted components. Do not exceed the rated torque capacity of the fastener by using extension tools on the hex key. Verify thread engagement depth and shaft hardness are appropriate for cup point contact before final tightening.
