Value Collection -42808-6 M30 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION -42808-6 is a metric hex socket cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. The screw features an M30 x 3.50 thread profile with a 120 mm length under head and is partially threaded, allowing for controlled clamp load in bolted joints. Manufactured from alloy steel to a 12.9 material grade, this fastener delivers high tensile strength suitable for demanding load-bearing connections. The black oxide finish provides moderate corrosion resistance and reduces light reflection on the fastener surface. Installation requires a hex key or Allen-type socket driver. Licensed mechanics, millwrights, and maintenance technicians are the primary installers.

This screw is suited for heavy-duty machinery assembly, die and mold work, hydraulic component mounting, and structural steel fabrication where metric high-strength fasteners are specified. Its partial threading allows the unthreaded shank to act as a precision locating element in close-tolerance bores. Conformance to DIN 912 and ISO 898-1 standards makes it appropriate for applications where fastener grade documentation is required. The M30 coarse thread pitch is the standard series for this diameter in metric fastener systems.

Key Features

• M30 x 3.50 coarse thread, 120 mm length under head
• Partially threaded shank for precision fit and controlled clamping
• Alloy steel construction rated to 12.9 material grade for high tensile strength
• Black oxide coating for moderate corrosion resistance and surface protection
• Hex socket drive for high-torque installation in confined spaces
• Conforms to DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard metric hex socket cap screw for use in applications specifying DIN 912 geometry and ISO 898-1 grade 12.9 fasteners with an M30 x 3.50 thread profile.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify thread engagement depth and bore condition before installation. Use a calibrated torque wrench and the appropriate hex key socket sized for M30 cap screws. Inspect the fastener seating surface and mating threads for damage or contamination before final assembly.
