Value Collection 532317BR Hex Socket Cap Screw M20x2.50

Product Description

The VALUE COLLECTION 532317BR is a partially threaded hex socket cap screw designed for high-strength fastening applications. Manufactured from alloy steel with a black oxide coating, it meets DIN 912 and ISO 898-1 fastener standards and carries a material grade of 12.9, indicating exceptional tensile and proof load capacity. The M20 x 2.50 thread size and 260 mm length under head make it suitable for heavy-duty structural and mechanical assemblies. Installation requires a hex key or Allen drive. This screw is specified and installed by millwrights, maintenance technicians, machinists, and industrial mechanics working on machinery, equipment frames, and structural connections.

This screw fits applications requiring a high-strength metric cap screw with a recessed hex drive, partial threading, and a standard cylindrical head profile. Common installation scenarios include machine bases, fixture plates, hydraulic component mounting, and general industrial equipment assembly where DIN 912 geometry is specified. The partial thread allows for precise clamping force and is preferred in applications where the unthreaded shank provides shear resistance between mating components.

Key Features

• Material grade 12.9 alloy steel for high tensile strength and proof load performance
• Partially threaded shank provides shear resistance in structural and mechanical joints
• Black oxide coating offers mild corrosion resistance and reduces surface glare
• Hex socket drive allows high torque application in confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards
• M20 x 2.50 thread pitch with 260 mm length under head for deep-reach applications

Compatibility

Designed as an OEM-style replacement or direct-fit metric cap screw for industrial machinery and equipment requiring a DIN 912 M20 x 2.50 partially threaded hex socket cap screw with a 12.9 material grade.

Installation Notes

Installation should be performed by qualified millwrights, machinists, or maintenance technicians familiar with metric fastener procedures. Verify mating thread condition and clean all threads before installation. Apply appropriate thread lubricant or fastener-grade compound as required by the joint specification. Always consult the equipment manufacturer's torque specification for M20 grade 12.9 hardware before tightening.
