Value Collection 42706 M3 X 0.50 Hex Socket Cap Screw 50-pack

Product Description

The VALUE COLLECTION 42706 is a metric hex socket cap screw engineered for precision fastening in mechanical assemblies, tooling fixtures, and industrial equipment. Threaded M3 x 0.50, it features a 25 mm length under head with partial threading along the shank. Manufactured from alloy steel with a black oxide coating, it meets DIN 912 dimensional standards and ISO 898-1 material grade 12.9 requirements. The grade 12.9 rating indicates high tensile strength, making this screw suitable for applications where clamping force and fatigue resistance are critical. Sold in a pack of 50.

This screw is used in light mechanical assemblies, machine tool components, jigs, fixtures, and precision equipment requiring a compact, low-profile fastener with an internal hex drive. The M3 thread size and 25 mm under-head length suit thin-section and close-tolerance applications across general manufacturing, maintenance, and equipment repair environments. The black oxide finish provides mild corrosion resistance and reduces light glare in optical or instrumentation setups. Each pack contains 50 screws, supporting both single-task repairs and small production runs.

Key Features

• M3 x 0.50 thread with 25 mm length under head for compact fastening applications
• Partially threaded shank provides a bearing surface for precise component alignment
• Grade 12.9 alloy steel construction delivers high tensile and proof load strength
• Black oxide coating offers mild corrosion resistance and a non-reflective finish
• Conforms to DIN 912 dimensional standard and ISO 898-1 material specification
• Internal hex socket drive accepts standard metric hex keys for torque application in tight spaces

Compatibility

Designed as an OEM-style replacement or stock fastener for M3 x 0.50 threaded applications conforming to DIN 912 and ISO 898-1 standards in general mechanical and industrial assemblies.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a calibrated metric hex key or hex bit driver sized for M3 socket cap screws. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque range for grade 12.9 M3 fasteners as specified by the equipment manufacturer or applicable industry standard. Inspect threads for damage prior to reuse in critical load-bearing joints.
