Value Collection A996747 M16x2 Hex Socket Cap Screw Din 912

Product Description

The VALUE COLLECTION A996747 is a metric hex socket cap screw engineered for high-stress fastening applications in industrial, mechanical, and structural assemblies. It features an M16 x 2.00 thread size with a 65 mm length under head and is partially threaded, providing secure clamping where full thread engagement is not required. The screw is manufactured from alloy steel to material grade 12.9, the highest standard tensile class for metric socket cap screws, and finished with a black oxide coating that provides moderate corrosion resistance and a clean appearance. Licensed machinists, millwrights, and maintenance technicians are the primary installers of this fastener type.

This screw is suited for applications requiring maximum tensile strength in compact spaces where a hex socket drive is preferred over a hex head. Typical use cases include machine frames, tooling fixtures, hydraulic components, and precision mechanical assemblies. The M16 x 2.00 thread pitch and partial threading make it appropriate for through-hole and counterbore installations in both ferrous and non-ferrous base materials. The black oxide finish is commonly specified in industrial environments where light oil retention is acceptable for corrosion management.

Key Features

• M16 x 2.00 metric thread size with 65 mm length under head
• Partially threaded shank for controlled clamping and shear resistance
• Alloy steel construction at material grade 12.9 for maximum tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket (Allen) drive for high-torque installation in tight clearances

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw, compatible with M16 x 2.00 threaded bores and counterbore applications in industrial machinery, fixtures, and structural assemblies requiring grade 12.9 fasteners.

Installation Notes

Installation is typically performed by machinists, millwrights, or mechanical maintenance technicians using a calibrated torque wrench and the appropriate metric hex key or Allen socket. Grade 12.9 fasteners should be torqued to the assembly manufacturer's specification for M16 hardware and should not be substituted with lower-grade fasteners in high-load joints. Inspect threads for contamination before installation, and apply a thread lubricant or anti-seize compound only when specified by the assembly documentation. Reuse of grade 12.9 fasteners in critical joints is generally not recommended after they have been torqued to yield.
