Value Collection 532539BR M18x2.5 Socket Cap Screw 120mm

Product Description

The VALUE COLLECTION 532539BR is an M18 x 2.50 hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from alloy steel to material grade 12.9, this fastener delivers exceptional tensile strength and clamping force suited for demanding service conditions. The black oxide coating provides moderate corrosion resistance and reduces light reflection on the fastener head. At 120 mm length under head with partial threading, it is well matched for through-bolt and tapped-hole configurations where a bearing surface is required along the shank. Installed using a hex key or Allen driver, it conforms to DIN 912 and ISO 898-1 standards.

This screw is used in heavy equipment manufacturing, machine tool assembly, hydraulic component mounting, and general industrial fabrication where a grade 12.9 alloy steel fastener is specified. The M18 x 2.50 thread pitch is a standard coarse metric thread, making it compatible with common M18 tapped components. Partially threaded shanks are preferred when load transfer through the shank body is needed rather than full thread engagement.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Black oxide finish for mild corrosion resistance and reduced surface reflectivity
• 120 mm length under head with partial threading for shank load applications
• M18 x 2.50 coarse metric thread conforms to DIN 912 and ISO 898-1 standards
• Hex socket drive accepts standard Allen keys and hex bit drivers

Compatibility

Designed as a standard DIN 912 hex socket cap screw for use in any M18 x 2.50 tapped hole or through-bolt application requiring a grade 12.9 alloy steel fastener.

Installation Notes

Installation is performed with a calibrated torque wrench and the appropriate hex key or hex bit socket sized for M18 socket cap screws. Always verify tapped hole depth and thread condition before installation. Apply thread lubricant or thread-locking compound per the equipment manufacturer specification where required. Ensure the mating surface is clean and flat to achieve proper clamp load and prevent fastener loosening under vibration.
