Holo-krome 76900 Hex Socket Cap Screw M36 X 4.00 80mm

Product Description

The HOLO-KROME 76900 is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and manufacturing environments. The screw features an M36 x 4.00 thread profile with an 80 mm length under head and is fully threaded along its entire shank. Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile and proof-load capacity suited for critical structural connections. A black oxide finish provides moderate corrosion resistance and a clean, low-reflectance appearance. Installation requires a hex (Allen) key or hex socket drive tool sized for M36 fasteners.

This cap screw is well suited for heavy-duty industrial machinery, structural assemblies, tooling fixtures, and equipment frames where high-clamp-load fasteners are required. The M36 size places this fastener in the large-diameter range, making it common in press frames, heavy fabrication equipment, and similar load-bearing applications. Fully threaded construction allows engagement from any point along the shank, offering flexibility in joint design.

Key Features

• M36 x 4.00 metric thread with 80 mm length under head
• Fully threaded shank for maximum thread engagement flexibility
• Alloy steel construction at material grade 12.9 for high tensile strength
• Black oxide finish for moderate corrosion resistance and reduced surface reflectance
• Hex socket (Allen) drive type for high-torque installation in confined spaces
• Meets ANSI B1.13M, ISO 4762, and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style and aftermarket replacement metric hex socket cap screw for M36 x 4.00 threaded assemblies conforming to ISO 4762 and ANSI B1.13M specifications.

Installation Notes

Installation should be performed by a qualified mechanic or industrial technician using a calibrated torque wrench and the appropriate hex socket drive tool. Always confirm mating thread condition and apply thread lubricant or thread-locking compound as required by the joint specification. Consult applicable engineering standards for torque values appropriate to grade 12.9 fasteners at this diameter. Never exceed the rated proof load of the fastener or the yield strength of the base material being joined.
