Value Collection 532490BR Hex Socket Cap Screw M30x3.5

Product Description

The VALUE COLLECTION 532490BR is a metric hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a black oxide finish, this screw meets DIN 912 and ISO 898-1 standards and carries a material grade of 12.9 — the highest common strength class for metric socket cap screws. It features an M30 x 3.50 thread and a 180 mm length under head with partial threading. At 2.69 pounds, this is a heavy-duty fastener suited for demanding load environments. Installation requires a standard hex (Allen) drive tool sized for M30 socket head fasteners.

This fastener is used in heavy machinery, structural steel connections, hydraulic equipment, press frames, and industrial fixtures where high clamp load and precise torque retention are required. The partially threaded shank provides a bearing surface that resists shear forces in bolted joints. The black oxide coating offers mild corrosion resistance and reduces surface glare in finished assemblies. Maintenance technicians, millwrights, and mechanical assemblers working with large-format metric hardware will encounter this fastener class in both OEM and MRO replacement applications.

Key Features

• M30 x 3.50 thread with 180 mm length under head for deep engagement in thick material stacks
• Grade 12.9 alloy steel construction provides high tensile and proof load capacity
• Partial threading preserves an unthreaded shank section for shear resistance
• Black oxide finish delivers mild corrosion resistance and a uniform matte appearance
• Conforms to DIN 912 dimensional standard and ISO 898-1 mechanical property requirements
• Hex socket (Allen) drive for high-torque installation in confined spaces

Compatibility

Designed as a standard DIN 912 metric socket cap screw for use in any application specifying an M30 x 3.50 Grade 12.9 fastener with a 180 mm length under head.

Installation Notes

Installation should be performed by qualified millwrights or mechanical assemblers familiar with high-strength metric fastener procedures. Use a properly rated hex key or socket driver to avoid rounding the drive recess. Grade 12.9 fasteners require calibrated torque tools to achieve proper clamp load — consult the equipment manufacturer's fastener specification for the applicable torque value. Clean and inspect mating threads before installation and apply thread lubricant or anti-seize only if specified by the assembly design.
