Value Collection MASC0040030CP M4 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION MASC0040030CP is a metric hex socket cap screw designed for use in mechanical assemblies, equipment fabrication, and general fastening applications. It features an M4 x 0.70 thread size with a 30 mm length under head and partial threading along the shank. Manufactured from 18-8 austenitic stainless steel (Material Grade A2) and conforming to DIN 912, this screw delivers corrosion resistance and consistent dimensional accuracy. It is installed using a hex allen key or hex bit driver and is suited for environments where moisture or chemical exposure rules out carbon steel fasteners.

This screw is commonly used in light mechanical assemblies, instrument panels, enclosures, pump housings, and process equipment where metric fasteners and corrosion resistance are required. The DIN 912 standard ensures dimensional interchangeability across manufacturers. Typical applications include HVAC equipment assembly, electrical panel fabrication, plumbing fixture mounting, and pool equipment enclosures where stainless hardware is preferred or specified. It is sold individually but requires a minimum order quantity of 100 units.

Key Features

• M4 x 0.70 metric thread for use in standard metric tapped holes
• 30 mm length under head with partial threading along the shank
• 18-8 austenitic stainless steel, Material Grade A2, for corrosion resistance
• DIN 912 standard ensures dimensional conformance and interchangeability
• Hex socket drive accepts standard allen keys and hex bit drivers
• Suitable for wet, humid, or chemically exposed environments

Compatibility

Designed as an OEM-style or aftermarket replacement hex socket cap screw for any application requiring a DIN 912 M4 x 0.70 partially threaded metric fastener.

Installation Notes

Installation is performed using a correctly sized hex allen key or hex bit driver to avoid rounding the socket. Verify the receiving tapped hole is clean and free of debris before fastening. Apply thread-locking compound only if specified by the equipment manufacturer, as stainless-to-stainless fasteners can be prone to galling without appropriate anti-seize lubricant. Follow applicable equipment service documentation and relevant industry codes when fastening structural or pressure-bearing components.
