Value Collection HC3XX18070-001BX M18 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION HC3XX18070-001BX is a fully threaded hex head cap screw manufactured to DIN 933 standards in Grade 316 austenitic stainless steel, classified as Material Grade A4. Sized at M18 x 2.50 thread pitch with a 70 mm length under head, this fastener is suited for structural and mechanical assemblies where corrosion resistance is a primary concern. The 27 mm hex drive allows installation with standard hex wrenches or impact tooling. Grade 316 stainless steel provides elevated resistance to chlorides and other corrosive media compared to Grade 304, making it a common selection for marine, chemical, and outdoor industrial environments.

This screw is appropriate for use in commercial and industrial applications where metric fasteners are specified and environmental exposure demands a corrosion-resistant material. Typical installation scenarios include equipment mounting, structural steel connections, piping support hardware, and outdoor or marine-grade assemblies. Trades including mechanical contractors, pipefitters, and industrial maintenance technicians regularly specify Grade 316 A4 hardware for wet, coastal, or chemically aggressive service conditions. The fully threaded shank allows engagement along the full length of the fastener for maximum thread grip in tapped or through-bolt applications.

Key Features

• Grade 316 austenitic stainless steel with A4 material classification for superior corrosion resistance
• Fully threaded shank per DIN 933 standard for complete thread engagement
• M18 x 2.50 metric thread size with 70 mm length under head
• 27 mm hex drive compatible with standard metric wrenches and impact sockets
• Bright uncoated finish — no additional coating to compromise dimensional tolerances
• Sold individually, no minimum order beyond single unit

Compatibility

Designed for use in any application requiring a fully threaded M18 x 2.50 metric hex head cap screw conforming to DIN 933. Compatible with standard M18 metric nuts, washers, and tapped components specified to DIN or ISO metric thread standards.

Installation Notes

Installation is performed with a 27 mm open-end, box, or socket wrench; impact tooling is acceptable for initial run-down when used with care to avoid thread galling, which is a known risk with stainless steel fasteners. Apply an anti-seize compound appropriate for stainless steel to reduce galling during installation and future removal. Verify thread engagement depth meets the requirements of the applicable structural or mechanical specification before final torque. Follow the relevant fastener standards and any project-specific engineering requirements for torque values, as no torque spec is provided with this SKU.
