Holo-krome 76396 Hex Socket Cap Screw M12 X 1.75 70mm

Product Description

The HOLO-KROME 76396 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. The screw features an M12 x 1.75 thread size with a 70 mm length under head, partial threading, and a hex drive socket for use with standard allen keys or hex bit drivers. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength suitable for demanding load-bearing connections. A black oxide finish provides mild corrosion resistance and a uniform matte appearance. This fastener conforms to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards.

This screw is suited for machine assembly, equipment manufacturing, tooling, and maintenance applications where high-clamp-load fasteners are required. It is commonly installed in metal-to-metal joints, jigs and fixtures, hydraulic components, and mechanical drive assemblies. The partial threading engages the full grip length, making it appropriate for through-bolt and clearance-hole configurations. Machinists, millwrights, and maintenance technicians are the typical installers in industrial and OEM settings.

Key Features

• M12 x 1.75 metric thread with 70 mm length under head
• Grade 12.9 alloy steel construction for maximum tensile and proof load capacity
• Partially threaded shank allows precise grip-length control in clearance-hole applications
• Hex socket drive compatible with standard allen keys and hex bit drivers
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Manufactured to ANSI B1.13M, DIN 912, ISO 4762, and ISO 898-1 standards

Compatibility

Designed as a standard DIN 912 and ISO 4762 metric hex socket cap screw for use in any application requiring an M12 x 1.75 grade 12.9 partially threaded fastener.

Installation Notes

Install using a properly sized hex key or socket bit driver rated for the torque demands of grade 12.9 fasteners. Degrease mating threads and apply appropriate thread lubricant or thread-locking compound as specified by the assembly engineer before installation. Never substitute a lower-grade fastener in applications engineered for grade 12.9 hardware. Follow applicable machine and structural assembly codes when determining torque values from published grade 12.9 fastener torque tables.
