Value Collection 42808 Hex Socket Cap Screw M30 X 3.50

Product Description

The VALUE COLLECTION 42808 is a metric hex socket cap screw designed for high-strength bolted assemblies in industrial, mechanical, and structural applications. Manufactured from alloy steel to material grade 12.9, it delivers exceptional tensile and proof load capacity relative to its size. The screw features an M30 x 3.50 thread profile with a 60 mm length under head and is fully threaded from head to tip. A black oxide finish provides mild corrosion resistance and reduces light reflection in service environments. This fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors using a standard hex key or socket drive tool.

This screw is suited for heavy-duty bolted connections in machine frames, press tooling, industrial equipment, and structural fixtures requiring a high-clamp-load fastener. The M30 x 3.50 thread is a coarse metric pitch commonly found in large-diameter machine components. Fully threaded geometry provides maximum thread engagement across the full 60 mm shank length, making it appropriate for applications where a partial-thread grip zone is not required. Sold in a package quantity of five.

Key Features

• Material grade 12.9 alloy steel for high tensile strength in demanding bolted joints
• M30 x 3.50 coarse metric thread profile fully threaded along the entire shank
• 60 mm length under head accommodates thick workpiece stacks
• Black oxide coating provides mild corrosion resistance and a low-reflectance finish
• Hex socket drive (DIN 912) for use with standard hex keys or hex bit sockets
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M30 x 3.50 threaded bores in industrial machinery, structural steel assemblies, and heavy equipment components requiring grade 12.9 fasteners.

Installation Notes

Installation should be performed by qualified mechanical technicians or millwrights familiar with metric fastener torque requirements for grade 12.9 hardware. Always de-energize or lock out equipment before replacing or installing fasteners in powered machinery. Use a calibrated torque wrench appropriate for large-diameter metric fasteners to achieve correct clamp load. Inspect threads and mating bores for damage or contamination before assembly.
