Value Collection -42808-2 M30x3.5 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42808-2 is a hex socket cap screw designed for high-strength fastening applications. Sized M30 x 3.50 with an 80 mm length under head, this fully threaded fastener is machined from alloy steel and finished with a black oxide coating for corrosion resistance. It carries a 12.9 material grade, the highest standard strength class for metric fasteners, making it suitable for demanding structural and mechanical assemblies. The drive type is hex socket, compatible with standard hex keys and Allen-type drive tools. It conforms to DIN 912 and ISO 898-1 fastener standards.

This screw is used in industrial machinery, structural steel assemblies, heavy equipment maintenance, and precision mechanical fabrication where high clamp load and reliable torque retention are required. The M30 thread size and 12.9 grade rating make it appropriate for applications under significant dynamic or static load. Maintenance technicians, millwrights, and industrial mechanics commonly install these fasteners in both OEM manufacturing and field service settings. The minimum order quantity is 5 pieces per order.

Compatibility

Designed as a standard metric hex socket cap screw conforming to DIN 912 and ISO 898-1, suitable for use in any application requiring an M30 x 3.50 fully threaded socket head cap screw at grade 12.9 strength.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with metric fastener torque specifications for grade 12.9 hardware. Always de-energize and lock out equipment before replacing structural fasteners in mechanical assemblies. Use a calibrated torque wrench and the correct hex socket bit to avoid cam-out or drive damage. Do not mix grade 12.9 fasteners with lower-grade hardware in the same joint.
