Value Collection 42709 M4x0.70 Hex Socket Cap Screw 10mm

Product Description

The VALUE COLLECTION 42709 is an M4 x 0.70 metric hex socket cap screw designed for precision fastening in mechanical assemblies, fixtures, and equipment. With a 10 mm length under head and full threading along the shank, this screw delivers consistent clamping force across the entire engaged thread length. Manufactured from alloy steel to material grade 12.9, it provides high tensile strength suited to demanding industrial and mechanical applications. The black oxide finish reduces surface corrosion and minimizes light reflection. Licensed tradespeople and assembly technicians rely on this fastener where tight tolerances and reliable torque retention are required.

This screw is appropriate for use in machine component assemblies, jigs, tooling plates, and general metalworking applications where metric M4 fasteners are specified. The hex socket drive requires a 3 mm hex key or Allen driver, making it suitable for recessed or countersunk installations where external wrench clearance is limited. It conforms to DIN 912 and ISO 898-1 fastener standards, making it a direct fit wherever those standards are called out in engineering drawings or maintenance documentation.

Key Features

• M4 x 0.70 metric thread with full threading along the shank for maximum thread engagement
• 10 mm length under head suits shallow through-hole and blind-hole fastening applications
• Alloy steel construction at material grade 12.9 provides high tensile and proof load strength
• Black oxide finish offers moderate corrosion resistance and a low-reflectance surface
• Hex socket drive (3 mm hex key) allows installation in tight or recessed spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards for broad dimensional compatibility

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any assembly specifying an M4 x 0.70 fully threaded socket head cap screw at 10 mm length under head.

Installation Notes

Installation requires a 3 mm hex key or Allen driver; use of the correct size driver prevents rounding of the socket recess. Tighten fasteners in a controlled sequence when used in multi-bolt patterns to ensure even clamping load. Grade 12.9 fasteners are not intended for welding or high-temperature applications that would compromise the alloy steel heat treatment. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.
