Value Collection HC3X04030-100BX M4 Hex Cap Screw 18-8 Ss Din 933

Product Description

The VALUE COLLECTION HC3X04030-100BX is a metric hex head cap screw designed for general-purpose fastening applications where corrosion resistance and dimensional consistency are required. This fully threaded fastener carries an M4 x 0.70 thread profile with a 30 mm length under head and a 7 mm hex drive. Manufactured from 18-8 austenitic stainless steel to Grade A2, it resists rust, oxidation, and mild chemical exposure. This package contains 100 pieces and is sold as a single box unit, making it suitable for bulk assembly, maintenance stock, or job-site replenishment. Machinists, millwrights, plumbers, and HVAC technicians commonly use fasteners of this type when assembling brackets, panels, and equipment housings.

This screw is suited for light- to medium-duty metric fastening in residential and commercial equipment assemblies. Its fully threaded shank provides maximum thread engagement in thin materials and short blind holes. Typical applications include control panel mounting, equipment enclosure assembly, and general mechanical assembly work where metric hardware is specified. The DIN 933 standard ensures dimensional interchangeability with other DIN 933-compliant components, making it a reliable choice when replacing or supplementing existing metric fastener inventories.

Key Features

• M4 x 0.70 thread profile with 30 mm length under head for compact through-fastening
• Fully threaded shank per DIN 933 standard for maximum thread engagement
• 18-8 austenitic stainless steel, Grade A2, for corrosion and oxidation resistance
• 7 mm hex drive compatible with standard metric wrenches and sockets
• Packaged in a 100-piece box for efficient bulk use and inventory restocking

Compatibility

Designed as a DIN 933-compliant metric hex head cap screw for use in any application requiring an M4 x 0.70 fully threaded fastener with a 30 mm length under head.

Installation Notes

Installation of metric fasteners should follow the equipment manufacturer torque specifications for M4 hardware. Use a properly sized metric wrench or socket to avoid rounding the 7 mm hex head. Verify thread engagement depth before final torque to prevent stripping in shallow tapped holes. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless or aluminum tapped holes.
