Value Collection -42706-1 Hex Socket Cap Screw M3 X 0.50

Product Description

The VALUE COLLECTION -42706-1 is a metric hex socket cap screw designed for precision fastening applications across industrial, mechanical, and trade assembly work. Threaded M3 x 0.50 with a 30 mm length under head, this screw is partially threaded and manufactured from alloy steel to material grade 12.9 — the highest standard strength classification for metric socket cap screws. A black oxide finish provides moderate corrosion resistance and reduces light reflection in finished assemblies. Each package contains 50 screws, making it practical for production, service, or maintenance work requiring consistent fastener supply.

This fastener suits applications where high clamp load in a small-diameter screw is required, such as machine tool components, fixture plates, jigs, precision instruments, and general mechanical assemblies. The M3 thread size and hex socket drive make it compatible with confined-space installations where a standard hex head wrench cannot be used. The partial thread design ensures positive engagement with tapped blind holes and provides accurate clamping without thread stripping. It conforms to DIN 912 and ISO 898-1 standards, making it interchangeable with other compliant M3 x 0.50 x 30 mm socket cap screws used in metric-standard equipment.

Key Features

• M3 x 0.50 metric thread with 30 mm length under head for precise fitment
• Grade 12.9 alloy steel construction delivers high tensile and yield strength
• Partially threaded shank for accurate clamping load in blind-hole applications
• Black oxide coating provides mild corrosion resistance and a clean appearance
• Hex socket drive accepts standard metric Allen keys and hex bit drivers
• Conforms to DIN 912 and ISO 898-1 fastener standards
• Sold in packs of 50 to support production and service volume needs

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a DIN 912-compliant M3 x 0.50 x 30 mm partially threaded hex socket cap screw in grade 12.9 alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with metric fastener torque requirements for grade 12.9 hardware. Always verify that the receiving tapped hole meets the M3 x 0.50 thread specification and is free of debris before installation. Use a properly sized hex key or socket bit to avoid rounding the drive recess. Do not substitute a lower-grade fastener in applications that specify grade 12.9 material.
