Value Collection 532521BR M18x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532521BR is a fully threaded hex socket cap screw designed for high-strength mechanical fastening applications. Built to DIN 912 and ISO 898-1 standards, this M18 x 2.50 screw measures 60 mm (approximately 2.36 inches) under the head and is machined from alloy steel with a material grade of 12.9, indicating exceptional tensile strength suitable for demanding structural and industrial assemblies. The black oxide finish provides a degree of corrosion resistance and reduces light reflection, making it appropriate for both functional and appearance-sensitive installations. This fastener is driven with a hex (Allen) key socket and is intended for installation by maintenance technicians, millwrights, machinists, and mechanical contractors.

This cap screw is used in a wide range of industrial, mechanical, and structural fastening scenarios where high clamping force and precision torque are required. Typical applications include machine frames, equipment housings, jigs, fixtures, and structural steel assemblies. The fully threaded shank engages the full depth of a tapped hole or nut, maximizing thread engagement and load distribution. This screw is appropriate for both original assembly and replacement fastening in commercial and industrial maintenance settings.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof load strength
• Fully threaded shank maximizes thread engagement in tapped holes and nuts
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Black oxide coating provides mild corrosion resistance and a non-reflective finish
• Hex socket drive allows high torque input with standard Allen keys or hex bit drivers
• UNSPSC Code 31161501 for streamlined procurement categorization

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw for use in any tapped M18 x 2.50 hole or with a matching M18 hex nut in industrial and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener torque requirements for Grade 12.9 hardware. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench and the appropriate hex key or Allen socket to achieve specified clamping force without stripping threads. De-energize or lock out any equipment before replacing fasteners in live machinery per applicable OSHA lockout/tagout procedures.
