Value Collection 42910 M4 Cup Point Set Screw Alloy Steel 50-pack

Product Description

The VALUE COLLECTION 42910 is an M4 x 0.70 x 5 mm cup point set screw manufactured from alloy steel to Grade 14.9 (45H), conforming to DIN 916. The cup point geometry bites into the mating surface for a secure, vibration-resistant hold without a protruding head. Driven by a 2 mm hex key, this fully threaded fastener is suited for securing collars, hubs, pulleys, and shafts in tight-clearance assemblies. Grade 14.9 (45H) alloy steel provides high tensile strength appropriate for demanding mechanical applications. Each package contains 50 pieces.

This set screw is used in light mechanical assemblies, HVAC equipment, pump housings, motor shaft retention, and general industrial fabrication where a flush or below-surface fastener is required. The metric M4 x 0.70 thread standard makes it a direct fit for metric-threaded bores in equipment manufactured to DIN or ISO specifications. Installers working on European-standard or metric-designated equipment will find this screw a routine stock item for service and assembly work.

Key Features

• M4 x 0.70 metric thread, 5 mm overall length
• Cup point design grips mating surfaces firmly to resist rotation and axial movement
• Grade 14.9 (45H) alloy steel construction for high tensile strength
• Conforms to DIN 916 fastener standard
• Hex drive requires a 2 mm hex key for installation and removal
• Sold in a 50-piece package for service stock and repetitive assembly tasks

Compatibility

Designed for metric-threaded M4 x 0.70 bores conforming to DIN or ISO thread standards. Suitable as a replacement or stock fastener in any assembly specifying a DIN 916 cup point set screw in M4 x 0.70 x 5 mm.

Installation Notes

Installation requires a 2 mm hex key; use a calibrated torque wrench or driver where the assembly specifies a torque value. De-energize and lock out any equipment before servicing fasteners on rotating components such as shafts or pulleys. Do not overtighten, as the cup point can deform soft shaft materials. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes for the installation environment.
