Value Collection 532515BR Hex Socket Cap Screw M18 X 2.50

Product Description

The VALUE COLLECTION 532515BR is an M18 x 2.50 metric hex socket cap screw rated to material grade 12.9, manufactured from alloy steel with a black oxide finish coating. It features a 40 mm length under head and is fully threaded along its entire shank. The black oxide coating provides a moderate level of corrosion resistance and reduces light reflection on the fastener surface. At 1.14 pounds per package of 10 pieces, this screw is suited for high-strength bolted joint applications where socket drive access is required. Installation is performed using a hex key or Allen driver of the appropriate metric size.

This fastener is commonly used in mechanical assemblies, machine frames, fixtures, tooling, and structural connections that demand high clamping force. The M18 x 2.50 thread pitch and 12.9 material grade make it appropriate for heavy industrial, manufacturing, and maintenance applications. It conforms to DIN 912 and ISO 898-1 standards, making it a recognized specification fastener for engineered assemblies. Minimum order quantity is 10 pieces per order.

Key Features

• M18 x 2.50 metric thread, fully threaded shank for maximum thread engagement
• 40 mm length under head provides defined grip length in bolted joints
• Grade 12.9 alloy steel for high tensile and proof load ratings
• Black oxide finish coating for mild corrosion resistance and reduced surface reflectivity
• Hex socket drive accepts standard metric hex keys and socket drive tools
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric socket cap screw for use in any application requiring an M18 x 2.50 fully threaded high-strength fastener conforming to ISO 898-1 grade 12.9 specifications.

Installation Notes

Installation is typically performed by mechanical technicians or millwrights using a calibrated torque wrench with a metric hex socket bit. Always verify that the mating tapped hole meets the appropriate M18 x 2.50 thread class before installation. Grade 12.9 fasteners should not be substituted into joints designed for lower-grade hardware without engineering review. De-energize and lock out any equipment before replacing or installing fasteners in live assemblies.
