Value Collection 120359 M4x0.70 Hex Socket Cap Screw 35mm

Product Description

The VALUE COLLECTION 120359 is an M4 x 0.70 metric hex socket cap screw designed for precision fastening applications requiring corrosion resistance and reliable clamping force. The screw measures 35 mm in length under the head and is manufactured from 18-8 austenitic stainless steel (Grade A2) with a bright, uncoated finish. Conforming to DIN 912, it is driven with a standard hex key (Allen wrench) and is suited for machine assembly, instrumentation, and structural fastening tasks where metric thread accuracy and material integrity matter. Installers in mechanical, plumbing, and industrial maintenance work routinely specify this fastener type for stainless-critical assemblies.

This screw is appropriate for use in residential and commercial mechanical assemblies, equipment mounting, and general fabrication where M4 metric threads are specified. The DIN 912 standard ensures dimensional consistency with other metric fasteners across European and ISO-aligned equipment. It is commonly used by mechanical contractors, millwrights, and field service technicians installing or servicing equipment panels, brackets, and component housings that require a low-profile socket-drive cap screw.

Key Features

• M4 x 0.70 metric thread, conforming to DIN 912 dimensional standard
• 35 mm length under head for deeper thread engagement in thicker materials
• 18-8 austenitic stainless steel, Grade A2 for corrosion resistance in wet or chemical-exposed environments
• Bright, uncoated finish — no plating to affect thread tolerance or introduce contamination risk
• Hex socket drive for high torque input in confined spaces using standard Allen keys

Compatibility

Designed as a standard DIN 912 metric replacement or general-use fastener for any assembly calling for an M4 x 0.70 hex socket cap screw in 18-8 stainless steel with a 35 mm length under head.

Installation Notes

Installation requires a metric hex key or Allen driver sized to the M4 socket cap head. Ensure mating threads are clean and free of debris before driving. Stainless-to-stainless thread galling is a known risk — apply anti-seize compound to the threads when fastening into stainless tapped holes. Follow applicable equipment manufacturer torque specifications for M4 hardware; do not over-torque, as 18-8 stainless fasteners have lower tensile strength than alloy steel equivalents.
