Value Collection 532475PR M30x3.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 532475PR is an M30 x 3.50 metric hex socket cap screw engineered for high-strength fastening applications. Built from alloy steel to material grade 12.9, this screw delivers exceptional tensile and proof load capacity suited for demanding mechanical and structural assemblies. The black oxide coating provides moderate corrosion resistance and reduces galling during installation. With a 120 mm length under head and partial threading, it is designed for clamped-joint applications where the unthreaded shank carries shear loads. Machinists, maintenance technicians, and millwrights install this fastener using a hex drive tool in pre-tapped or through-bolted assemblies.

This cap screw is used in industrial machinery, heavy equipment, structural steel fabrication, and OEM mechanical assemblies requiring a metric DIN 912 fastener. The M30 thread size and 120 mm length under head suit large-bore bolt patterns common in gearboxes, hydraulic manifolds, press frames, and heavy-duty flanged connections. Partial threading allows the unthreaded grip length to span the joint interface, maintaining clamp load under dynamic loads. Installation follows DIN 912 and ISO 898-1 standards, making it compatible with metric hardware systems specifying grade 12.9 socket head cap screws.

Key Features

• Alloy steel construction rated to material grade 12.9 for high tensile and proof load performance
• M30 x 3.50 thread form with 120 mm length under head — partially threaded for shear-load applications
• Black oxide finish reduces surface friction and provides light corrosion resistance
• Hex socket drive (internal hex) for high-torque installation with standard Allen or hex bit tooling
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Sold individually — quantity of one per package

Compatibility

Designed as a DIN 912 metric hex socket cap screw conforming to ISO 898-1 grade 12.9 specifications, suitable for any metric-threaded application requiring an M30 x 3.50 partially threaded socket head fastener.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized hex key or socket bit rated for high-torque applications. Ensure the mating threaded hole or nut meets grade 12.9 load requirements before assembly. Apply appropriate thread lubricant or anti-seize compound per the equipment manufacturer's specifications to achieve accurate clamp load. Do not use impact tools without torque-limiting control, as over-torquing grade 12.9 fasteners can cause brittle fracture.
