Value Collection A996754 Hex Socket Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION A996754 is an M20 x 2.50 hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. The screw features a 140 mm length under head with partial threading and is manufactured from alloy steel to material grade 12.9, the highest standard strength class for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces light reflection on exposed hardware. Installation requires a hex socket drive tool. This screw conforms to DIN 912 and ISO 898-1 fastener standards, making it a reliable choice for precision engineering work.

This fastener is suited for heavy-duty bolted connections where a high clamp load is required. The partial thread design concentrates grip in the shank, making it appropriate for applications involving shear loads or precision alignment. Common install scenarios include machine frames, tooling fixtures, hydraulic equipment mounts, and industrial machinery assemblies. Each package contains 5 screws.

Key Features

• M20 x 2.50 thread size with 140 mm length under head
• Partially threaded shank for shear-load and alignment-critical joints
• Alloy steel construction rated to material grade 12.9 for maximum tensile strength
• Black oxide coating for mild corrosion resistance and reduced surface reflectivity
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket drive for high-torque installation with standard Allen or hex-key tooling

Compatibility

Designed as a standard metric replacement or new-installation fastener for any application requiring an M20 x 2.50 hex socket cap screw meeting DIN 912 and ISO 898-1 specifications.

Installation Notes

Installation is performed by mechanical maintenance technicians or millwrights using a calibrated torque wrench and the appropriate hex socket bit. Always de-energize and lock out the equipment being serviced before fastener installation or removal. Grade 12.9 fasteners are sensitive to hydrogen embrittlement; avoid re-use of previously torqued high-strength fasteners in critical joints unless approved by engineering. Follow the equipment manufacturer or applicable industry standard for torque specifications, as values vary by joint material and lubrication condition.
