Holo-krome 76204 Hex Socket Cap Screw M6 X 1.00 60mm

Product Description

The HOLO-KROME 76204 is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, equipment manufacturing, and industrial maintenance. The fastener features an M6 x 1.00 thread size with a 60 mm length under head and is partially threaded, making it suitable for clamping applications that require a smooth shank section beneath the head. Manufactured from alloy steel to a Grade 12.9 material standard and finished with a black oxide coating, this screw delivers high tensile strength with moderate corrosion resistance. It is driven with a standard hex (Allen) key. Licensed trades and industrial maintenance professionals are the primary installers.

This screw is well suited for precision mechanical assemblies, machine tool fixtures, die sets, and structural fastening applications where Grade 12.9 alloy steel strength is required. The partial threading is appropriate for through-hole and clearance-fit installations where shank contact with the hole wall improves load distribution. The black oxide finish reduces light reflection and provides a measure of surface protection in light-duty environments. Sold in a minimum order quantity of 100 pieces per order.

Key Features

• M6 x 1.00 thread size per ANSI B1.13M, DIN 912, and ISO 4762 standards
• Grade 12.9 alloy steel construction for high tensile and proof load capacity
• Partial threading with 60 mm length under head for shank-bearing applications
• Black oxide finish for reduced reflectivity and light surface protection
• Hex socket drive compatible with standard metric Allen keys and hex bit drivers
• Meets ISO 898-1 mechanical property requirements for high-strength fasteners

Compatibility

Designed as a standard metric hex socket cap screw per DIN 912 and ISO 4762, suitable for any application specifying an M6 x 1.00 Grade 12.9 partially threaded socket head cap screw.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a calibrated torque wrench and the appropriate metric hex key or hex bit. De-energize and lock out all equipment before fastener replacement in live machinery. Grade 12.9 fasteners should not be substituted with lower-grade hardware, and reuse of fasteners in critical joints is generally not recommended. Consult the equipment manufacturer torque specification table for the correct installation torque for M6 Grade 12.9 fasteners in the specific joint material.
