Value Collection 532324PR Hex Socket Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 532324PR is a partially threaded hex socket cap screw designed for high-strength bolted assemblies. Manufactured from alloy steel with a black oxide finish, it meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9 — the highest common grade for metric socket cap screws. The M20 x 2.50 thread and 300 mm length under head suit deep-reach clamping applications where standard-length fasteners fall short. Licensed trades and industrial maintenance technicians use this screw in structural, mechanical, and machine assembly work where torque retention and tensile strength are critical.

This fastener is suited for demanding industrial and mechanical installations requiring a high-grade metric socket cap screw. The partial threading allows the unthreaded shank to act as a precision locating feature within a bored hole, improving alignment and shear resistance. At 1.74 pounds per unit, it is a substantial fastener appropriate for heavy equipment, fixtures, die sets, and structural machinery frames. The hex socket drive allows torque application with an Allen key or hex bit driver in confined spaces where a hex head wrench would not fit.

Key Features

• Grade 12.9 alloy steel construction for high tensile and proof-load strength
• Black oxide coating provides mild corrosion resistance and reduces light reflection in service
• Partial threading allows shank to serve as a precision locating and shear pin
• Hex socket drive accepts standard Allen keys and hex bit drivers
• Meets DIN 912 and ISO 898-1 dimensional and mechanical property standards
• M20 x 2.50 thread with 300 mm length under head for deep-reach clamping

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M20 x 2.50 threaded bores in industrial machinery, structural assemblies, and heavy equipment requiring grade 12.9 fasteners.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or industrial technicians using a calibrated torque wrench and the appropriate hex key or socket bit. De-energize and lock out all equipment before fastener installation or removal per applicable OSHA lockout/tagout procedures. Grade 12.9 fasteners should not be substituted with lower-grade hardware, and thread engagement depth should meet engineering specifications for the application. Black oxide finish is not a heavy-duty corrosion barrier — apply a thread lubricant or anti-seize compound where moisture or corrosion is a concern.
