Value Collection 533001P M3x0.50 Cup Point Set Screw 3mm

Product Description

The VALUE COLLECTION 533001P is an M3x0.50 metric coarse cup point set screw intended for mechanical assemblies where a compact, headless fastener is required to secure a component against a shaft or within a threaded bore. The screw measures 3mm overall length (OAL) and is manufactured from Grade 14.9 (45H) alloy steel, providing high tensile strength suited to demanding clamping and locking applications. A 1.5mm hex key drive is used for installation. This fastener is a standard tool for machinists, millwrights, and mechanical contractors working on motion control, pump, motor, or shaft-collar assemblies.

Cup point set screws in the M3x0.50 thread class are commonly used in light-duty to medium-duty mechanical assemblies across residential and commercial equipment. Typical applications include securing set collars, shaft couplings, pulleys, and similar rotary components in HVAC equipment, pumps, and general industrial machinery. The cup point geometry creates a small indentation on the mating surface for positive retention under vibration and torque loading.

Key Features

• M3x0.50 metric coarse thread for standard metric mechanical assemblies
• 3mm overall length for compact, low-profile fastening in tight clearances
• Grade 14.9 (45H) alloy steel construction for high clamping strength
• Cup point geometry provides positive bite into mating shaft surface under load
• 1.5mm hex key drive for precise installation torque control

Compatibility

Designed as an OEM-style replacement or stock fastener for any mechanical assembly requiring an M3x0.50 metric coarse thread cup point set screw with a 3mm OAL and 1.5mm hex key drive.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a 1.5mm hex key or T-handle driver. Ensure the mating shaft and threaded bore are clean and free of debris before installation. De-energize and lockout any rotating equipment before accessing shaft collars or couplings. Thread engagement and seating torque should follow the fastener manufacturer or equipment OEM specification for M3 alloy set screws.
