Value Collection 532553BR M18x2.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532553BR is a metric hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and structural connections. It features an M18 x 2.50 thread size with a 200 mm length under head and is partially threaded, making it well-suited for through-bolt and clamped-joint configurations. Manufactured from alloy steel to material grade 12.9, this screw delivers exceptional tensile and yield strength. A black oxide finish provides moderate corrosion resistance and reduces surface reflectivity. It is driven by a hex socket, requiring an appropriately sized Allen key or hex bit driver. Machinists, maintenance technicians, and industrial assemblers are the primary installers.

This screw is appropriate for industrial, manufacturing, and maintenance environments where high-strength metric fasteners are required. Partially threaded cap screws at this size and grade are commonly used in machine frames, fixtures, dies, molds, and heavy equipment assemblies. Conformance to DIN 912 and ISO 898-1 standards ensures dimensional and mechanical compatibility with metric fastener systems used across North American and international manufacturing operations.

Key Features

• M18 x 2.50 metric thread for high-load fastening applications
• 200 mm length under head with partial threading for clamped-joint use
• Alloy steel at grade 12.9 for maximum tensile strength in the metric fastener class
• Black oxide finish for surface protection and low reflectivity
• Hex socket drive for torque application with standard Allen keys or hex bits
• Conforms to DIN 912 and ISO 898-1 standards

Compatibility

Designed as an OEM-style replacement or direct-fit metric fastener for machinery and assemblies requiring DIN 912-compliant M18 x 2.50 partially threaded hex socket cap screws at grade 12.9.

Installation Notes

Installation should be performed by qualified machinists or mechanical technicians familiar with metric fastener torque requirements for grade 12.9 hardware. Always clean and inspect the threaded bore before installation. Use a calibrated torque wrench with an appropriate hex bit to achieve proper clamp load without overloading the joint. Do not mix metric and unified thread fasteners in the same assembly.
