Value Collection 461367PS Hex Head Cap Screw M20 X 2.50

Product Description

The VALUE COLLECTION 461367PS is a metric hex head cap screw designed for heavy-duty bolted assemblies requiring high tensile strength and precise fastening. Manufactured from Grade 10.9 steel with a bright uncoated finish, this screw meets DIN 931 and ISO 4014 standards for partially threaded hex bolts. The M20 x 2.50 thread profile and 220 mm length under head make it suited for through-bolt applications in thick structural members, machinery frames, and industrial equipment. Installation requires a 30 mm hex wrench or socket. The part weighs approximately 1.3 pounds. Machinists, millwrights, and industrial maintenance technicians are the typical installers for this fastener class.

This cap screw is used in metric bolted joint applications across general industrial, heavy equipment, and structural assembly environments. The partially threaded shank provides a smooth bearing surface through the joint material, which is advantageous in shear-loaded connections. It is appropriate for both original equipment assembly and field maintenance or repair work where a high-strength metric fastener is required.

Key Features

• Grade 10.9 steel construction provides high tensile and proof load strength for demanding applications
• Partially threaded shank allows the unthreaded portion to bear shear loads across the joint interface
• Bright uncoated finish maintains dimensional consistency and is suitable for use with standard metric nuts and washers
• Conforms to DIN 931 and ISO 4014 standards for interchangeability and dimensional accuracy
• 30 mm hex drive is compatible with standard metric sockets and open-end wrenches
• 220 mm length under head accommodates thick structural sections and stacked assemblies

Compatibility

Designed as a standard DIN 931 and ISO 4014 compliant partially threaded hex cap screw for M20 x 2.50 metric bolted assemblies in industrial, structural, and heavy equipment applications.

Installation Notes

Installation should be performed by a qualified millwright, mechanic, or maintenance technician familiar with metric fastener standards. Apply appropriate thread lubrication or anti-seize compound as required by the joint specification, and torque to the value specified in the applicable engineering documentation for Grade 10.9 fasteners. Ensure mating nuts and threaded holes conform to M20 x 2.50 metric thread class before assembly. Inspect the screw for damage or thread deformation before use and do not reuse fasteners that have been torqued beyond yield.
