Value Collection 532511BR M18x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532511BR is a fully threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at M18 x 2.50 metric thread with a 30 mm length under head, this fastener is manufactured from alloy steel to Material Grade 12.9, the highest common strength classification for metric socket cap screws. The black oxide finish provides moderate corrosion resistance and reduces light reflection in finished assemblies. It is driven with a hex key and conforms to DIN 912 and ISO 898-1 standards. Maintenance technicians, machine builders, and millwrights are the primary installers.

This screw is suited for use in heavy-duty bolted joints where high clamping force and precise torque control are required. Grade 12.9 alloy steel construction makes it appropriate for demanding applications such as hydraulic component mounting, machine frames, and tooling fixtures. The M18 x 2.50 thread pitch is a standard coarse metric pitch, widely used in European-standard and ISO-specification machinery. This SKU ships in a package quantity of 1 with a minimum order quantity of 10 units.

Key Features

• M18 x 2.50 metric coarse thread, fully threaded along the 30 mm length under head
• Alloy steel construction rated to Material Grade 12.9 for maximum tensile and proof load
• Black oxide finish for mild corrosion resistance and low-reflectivity appearance
• Hex socket (Allen key) drive for high torque application in confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any M18 x 2.50 threaded hole requiring a Grade 12.9 fastener.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate size hex key or socket driver. Always ensure the mating threaded hole is clean, undamaged, and of compatible thread class before assembly. Do not mix Grade 12.9 fasteners with lower-grade hardware in the same joint without engineering review. Apply thread lubricant or anti-seize only if called for by the equipment manufacturer specification.
