Value Collection 532541BR Hex Socket Cap Screw M18x2.50

Product Description

The VALUE COLLECTION 532541BR is a metric hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features an M18 x 2.50 thread profile with a 130 mm length under head and is partially threaded for controlled engagement depth. Built from alloy steel and finished with a black oxide coating, it meets DIN 912 and ISO 898-1 fastener standards at a 12.9 material grade, making it suitable for demanding torque and load requirements where precision and strength are critical.

This fastener is commonly used by machinists, maintenance technicians, and mechanical assembly professionals in manufacturing facilities, heavy equipment maintenance, and precision machine building. The hex socket drive allows installation in recessed or space-constrained locations where a standard hex head wrench cannot reach. Its partial threading suits applications where the shank must bear shear loads or where the fastener passes through clearance holes before engaging a threaded bore.

Key Features

• M18 x 2.50 metric thread with 130 mm length under head
• Partially threaded shank for shear-load and clearance-hole applications
• Alloy steel construction rated at material grade 12.9 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduced glare
• Hex socket drive for use in confined or recessed installation points
• Manufactured to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for use in any application requiring an M18 x 2.50 thread pitch and a 130 mm length under head in a partially threaded configuration.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using a calibrated torque wrench with the appropriate hex socket bit. Ensure the mating threaded bore is clean and free of debris before driving the fastener. Because the shank is partially threaded, confirm thread engagement depth meets the requirements of the joint design before applying final torque. Grade 12.9 fasteners should not be substituted with lower-grade hardware in high-load or safety-critical joints.
