Value Collection -42797-3 Hex Socket Cap Screw M16 X 2.00

Product Description

The VALUE COLLECTION -42797-3 is a metric hex socket cap screw designed for high-strength mechanical fastening applications. Manufactured from alloy steel with a black oxide finish, this screw meets DIN 912 and ISO 898-1 fastener standards and carries a material grade of 12.9, indicating exceptional tensile strength suitable for demanding structural and industrial assemblies. The M16 x 2.00 thread size with a 70 mm length under head makes it well suited for medium-to-heavy fastening tasks. Installation requires a hex drive tool. This fastener is used by machinists, millwrights, and maintenance technicians working on equipment assemblies, tooling fixtures, and structural mechanical components.

This screw is appropriate for industrial, commercial, and heavy-duty mechanical applications where a high-strength metric fastener is required. The partially threaded shank is typical for applications where precise clamping length and shear strength are important, such as flanged joints, machine frames, and press-fit assemblies. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it a common choice in both shop and field environments.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish provides mild corrosion resistance and a low-reflectance appearance
• Partially threaded shank supports accurate clamping and shear load resistance
• Hex socket drive for high-torque installation with standard Allen or hex keys
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any application requiring an M16 x 2.00 thread pitch fastener with a 70 mm length under head.

Installation Notes

Installation should be performed by a qualified mechanic or technician using a calibrated torque wrench and the appropriate hex key or Allen socket sized for an M16 socket cap screw. Always degrease mating threads and apply thread lubricant or thread-locking compound per the assembly specification before torquing. De-energize and lock out all equipment per applicable OSHA lockout-tagout procedures before working on any mechanical assembly. Grade 12.9 fasteners should not be substituted with lower-grade hardware without engineering review.
