Value Collection 532678PR M36 Hex Socket Cap Screw 130mm

Product Description

The VALUE COLLECTION 532678PR is an M36 x 4.00 mm hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw is manufactured from alloy steel to a material grade of 12.9, making it suitable for demanding clamping and bolting scenarios where tensile strength and fatigue resistance are critical. The black oxide finish provides a degree of corrosion resistance and reduces light reflection in finished assemblies. The fastener conforms to DIN 912 and ISO 898-1 standards and is driven with a hex socket tool. Installation is typically performed by machinists, millwrights, maintenance technicians, and mechanical contractors.

This screw is appropriate for heavy industrial and mechanical applications requiring a large-diameter metric fastener. With a 130 mm length under head and partial threading, it provides a clean shank section for shear-loaded connections and precise joint clamping. Partial threading is common in bolted flange assemblies, machinery mounts, and structural steel connections where the unthreaded shank must pass through a clearance hole before engaging a threaded bore or nut.

Key Features

• M36 x 4.00 mm thread size for large-diameter bolted connections
• Grade 12.9 alloy steel construction for maximum tensile and proof load capacity
• Partially threaded shank accommodates shear-loaded joint designs
• Black oxide finish for mild corrosion resistance and surface hardness retention
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Hex socket drive for high-torque wrench access in confined spaces

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for industrial and mechanical assemblies requiring an M36 x 4.00 mm thread form and 130 mm length under head.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights using a calibrated torque wrench and the appropriate hex socket bit for M36 fasteners. Always de-energize and lockout-tagout any machinery before servicing bolted connections on equipment. Thread engagement, lubrication conditions, and joint design should be verified against the applicable engineering specification before final torque is applied. Grade 12.9 fasteners should not be substituted for lower-grade hardware without engineering review.
