Value Collection 532681BR M36x4 Socket Cap Screw 140mm

Product Description

The VALUE COLLECTION 532681BR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features an M36 x 4.00 thread specification with a 140 mm length under head and partial threading along the shank. Manufactured from alloy steel with a black oxide finish coating, this screw meets DIN 912 and ISO 898-1 standards at a material grade of 12.9, the highest standard grade for metric socket cap screws. The internal hex drive requires a matching hex key or Allen-type socket for installation. Licensed tradespeople, millwrights, and mechanical contractors are the typical installers.

This fastener is suited for heavy-duty bolted connections where high clamp load and reliable torque retention are critical. The M36 x 4.00 thread profile and 140 mm under-head length make it appropriate for large-bore flanged joints, machinery bases, structural steel connections, and heavy equipment frames. The partial threading leaves a smooth shank section that aids in precise alignment and shear-load distribution between mated components. The black oxide coating provides mild corrosion resistance in indoor or sheltered environments.

Key Features

• M36 x 4.00 metric thread for high-load bolted connections
• 140 mm length under head with partial threading for shank alignment and shear resistance
• Grade 12.9 alloy steel construction for maximum tensile and proof strength
• Black oxide coating provides mild corrosion resistance and reduces galling during assembly
• Internal hex drive compatible with standard hex key and socket tooling
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style and replacement-fit metric hex socket cap screw for any application requiring an M36 x 4.00 DIN 912 grade 12.9 fastener.

Installation Notes

Installation should be performed by a qualified millwright, machinist, or mechanical contractor familiar with metric fastener torque procedures for grade 12.9 hardware. De-energize all equipment and relieve any hydraulic or pneumatic pressure before disassembling bolted joints. Use calibrated torque tooling appropriate for M36 fasteners and apply thread lubricant or anti-seize as required by the service specification. Do not substitute a lower-grade fastener in any joint originally designed for grade 12.9 hardware.
