Value Collection 42718 M4x0.70 Hex Socket Cap Screw 45mm

Product Description

The VALUE COLLECTION 42718 is a metric hex socket cap screw designed for precision fastening applications in mechanical assemblies, tooling fixtures, and equipment fabrication. Sized at M4 x 0.70 mm thread pitch with a 45 mm length under head, this fastener is partially threaded and driven with a hex socket key. Manufactured from alloy steel at material grade 12.9, it delivers high tensile strength suited for clamping and load-bearing joints. The black oxide finish provides light corrosion resistance and reduces light glare on exposed hardware. It conforms to DIN 912 and ISO 898-1 fastener standards.

This screw is commonly used in machinery maintenance, jig and fixture assembly, mold tooling, and general mechanical fabrication where a flush or recessed drive profile is required. The M4 thread size is a standard choice for compact assemblies in both light industrial and precision instrument applications. Machinists, millwrights, equipment technicians, and maintenance mechanics regularly specify this fastener type for controlled-torque joint work.

Key Features

• M4 x 0.70 mm thread pitch per DIN 912 and ISO 898-1 standards
• 45 mm length under head, partially threaded for controlled engagement depth
• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish for light corrosion resistance and reduced surface glare
• Hex socket drive for high-torque input in recessed or confined spaces

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any M4 x 0.70 mm tapped hole requiring a grade 12.9 fastener with 45 mm grip length.

Installation Notes

Installation requires a properly sized hex key or Allen driver matched to the M4 socket head. Ensure the mating tapped hole is clean and free of debris before driving. Apply thread-locking compound or specified preload torque per the equipment manufacturer guidelines where vibration is a concern. Always de-energize or depressurize any system before performing fastener service on live assemblies.
