Value Collection HC3XX04050-025BX Hex Head Cap Screw M4

Product Description

The VALUE COLLECTION HC3XX04050-025BX is a fully threaded hex head cap screw designed for metric fastening applications requiring corrosion resistance and dimensional precision. Manufactured from Grade 316 austenitic stainless steel (Grade A4), this screw delivers strong resistance to chlorides, acids, and marine environments. The M4 x 0.70 thread profile runs the full length of the 50 mm shank, and the 7 mm hex drive accommodates standard metric wrenches and sockets. Compliant with DIN 933, it meets recognized dimensional and mechanical standards for metric fasteners. Licensed tradespeople and fabricators working in harsh or wet environments specify this grade for its superior corrosion performance over 18-8 stainless.

This screw is suited for use in HVAC equipment assemblies, plumbing fixture mounting, electrical enclosure fabrication, pool and spa equipment, and marine or coastal installations where salt-air or chemical exposure is a concern. Its fully threaded shank makes it appropriate for through-hole applications or shorter clamping lengths where full thread engagement is required. The DIN 933 standard ensures interchangeability with other compliant metric hardware across equipment brands and panel assemblies.

Key Features

• Grade 316 austenitic stainless steel (A4) for superior chloride and acid resistance
• Fully threaded shank provides maximum thread engagement across the entire 50 mm length
• M4 x 0.70 mm thread pitch conforms to standard metric coarse series
• 7 mm hex drive compatible with standard metric wrenches and box-end tools
• DIN 933 compliant for dimensional interchangeability with metric hex cap screws
• Bright uncoated finish maintains base material properties without additional plating

Compatibility

Designed as a DIN 933 compliant M4 x 0.70 hex head cap screw for use in any application requiring a fully threaded metric fastener with a 7 mm hex drive and Grade 316 stainless steel construction.

Installation Notes

Installation is performed by qualified tradespeople using standard metric hand tools or power drivers with a 7 mm hex socket. Verify thread fit and clearance hole sizing before final assembly. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-humidity applications to minimize galvanic corrosion risk. Apply an anti-seize compound rated for stainless steel if the fastener will be exposed to high heat or repeated removal cycles, as austenitic stainless can gall without lubrication.
