Value Collection 156 M4 X 0.70 X 16mm Hex Cap Screw 316 Ss

Product Description

The VALUE COLLECTION 156 is a fully threaded hex head cap screw designed for metric fastening applications where corrosion resistance is critical. Manufactured from Grade 316 austenitic stainless steel (Grade A4), this fastener offers superior resistance to chlorides, salt water, and chemical exposure compared to standard 304-grade hardware. The M4 x 0.70 thread pitch and 16 mm length under head make it suited to precision assemblies where dimensional accuracy and material integrity must be maintained. The 7 mm hex drive allows installation with standard metric wrenches and hex keys. These screws are supplied uncoated, meeting DIN 933 dimensional standards.

This fastener is used across a wide range of trade and industrial applications including HVAC equipment assembly, plumbing fixture mounting, marine hardware, food-service equipment, and outdoor electrical enclosures where stainless steel is specified. Its fully threaded shank makes it particularly useful in thin-material or close-tolerance applications where partial threading would reduce engagement length. Licensed tradespeople and maintenance technicians specifying metric hardware for corrosive environments will find this screw a direct DIN 933 conforming solution.

Key Features

• Grade 316 austenitic stainless steel (Grade A4) for elevated corrosion resistance in wet and chemical environments
• Fully threaded shank provides maximum thread engagement across the full 16 mm length
• M4 x 0.70 metric thread pitch per DIN 933 standard
• 7 mm hex drive compatible with standard metric wrenches and box-end tooling
• Uncoated finish eliminates coating thickness variation for tight-tolerance assemblies
• Minimum order quantity of 25 pieces supports both single-job and bulk service use

Compatibility

Designed as an OEM-style and general-purpose replacement or specification fastener for any application requiring a DIN 933 fully threaded metric hex head cap screw in M4 x 0.70 thread size with Grade 316 stainless steel material.

Installation Notes

Installation is performed by mechanical and maintenance technicians using standard metric hand tools or power drivers fitted with appropriate metric hex sockets. Always verify thread engagement depth and mating thread material compatibility before installation, particularly in dissimilar-metal assemblies where galvanic corrosion between stainless steel and aluminum or carbon steel may be a concern. Apply appropriate anti-seize compound when fastening stainless-to-stainless connections to prevent galling. Follow applicable equipment manufacturer torque specifications and relevant codes for the installation environment.
