Value Collection 42705 M3x0.50 Hex Socket Cap Screw 50pk

Product Description

The VALUE COLLECTION 42705 is a fully threaded hex socket cap screw sized M3 x 0.50 with a 12 mm length under the head. Manufactured from alloy steel and finished with black oxide coating, this fastener meets DIN 912 and ISO 898-1 standards at a material grade of 12.9. The 12.9 grade designation indicates very high tensile strength, making it suitable for demanding mechanical assemblies where high clamping force in a small fastener is required. Black oxide provides a degree of corrosion resistance and reduces light reflection. This screw is installed using a hex socket driver or Allen wrench and is used by mechanical technicians, millwrights, and maintenance tradespeople across industrial and commercial applications.

The M3 x 0.50 thread pitch and 12 mm under-head length make this screw appropriate for compact assemblies, precision equipment, and close-tolerance mechanical components. It is commonly used in HVAC equipment panels, pump and motor housings, electrical enclosures, and general mechanical assemblies where a low-profile, high-strength fastener is needed. Each package contains 50 screws, sold as a single package unit.

Key Features

• M3 x 0.50 thread with 12 mm length under head for compact, tight-clearance applications
• Grade 12.9 alloy steel for very high tensile and proof load strength
• Fully threaded shank provides maximum thread engagement across the length
• Hex socket (Allen) drive reduces cam-out during high-torque installation
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• Meets DIN 912 and ISO 898-1 fastener standards for dimensional and mechanical consistency

Compatibility

Designed as a standard M3 x 0.50 DIN 912 hex socket cap screw compatible with any threaded hole or insert sized for M3 x 0.50 metric thread.

Installation Notes

Install with a calibrated hex socket key or Allen wrench sized for the M3 socket head. Power down and de-energize any electrical or mechanical equipment before fastener replacement or removal. Follow applicable equipment manufacturer torque specifications for grade 12.9 hardware. Wear appropriate PPE when working with high-strength fasteners under load.
