Value Collection 42721 M5x0.80 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 42721 is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and industrial equipment. Sized M5 x 0.80 with a 12 mm length under head, this fastener is fully threaded along its entire shank. It is manufactured from alloy steel and finished with a black oxide coating, providing moderate corrosion resistance and a low-reflectivity surface. The material grade is 12.9, indicating a high-strength fastener suitable for applications requiring reliable clamping force under load. Installation requires a hex key or Allen driver. Minimum order quantity is 50 pieces per order.

This screw is suited for use in general industrial, mechanical, and maintenance applications where a compact, high-strength metric fastener is needed. The M5 thread size and 12 mm under-head length make it a common choice in light machinery, hydraulic component mounting, equipment enclosures, and precision assemblies. Fully threaded geometry provides maximum thread engagement across the full shank length, which is preferred when threading into shallow or thin material. Trades including millwrights, maintenance technicians, and mechanical assembly professionals commonly use this fastener size.

Key Features

• M5 x 0.80 metric thread, fully threaded shank for maximum engagement
• 12 mm length under head for standard shallow-to-medium depth fastening
• Alloy steel construction with 12.9 material grade for high clamping strength
• Black oxide finish for moderate corrosion resistance and reduced surface glare
• Hex socket drive type compatible with standard Allen keys and hex bit drivers
• Meets DIN 912 and ISO 898-1 fastener standards

Compatibility

Designed as a standard DIN 912 metric hex socket cap screw suitable for M5 x 0.80 threaded holes in industrial machinery, fixtures, and mechanical assemblies.

Installation Notes

Installation requires a properly sized hex key or socket hex bit driver. Always ensure the receiving threaded hole is clean, undamaged, and cut to the correct M5 x 0.80 pitch before driving. Do not exceed the torque rating appropriate for a grade 12.9 M5 fastener as specified by the equipment manufacturer. Wear appropriate PPE when working with high-strength fasteners in pressurized or high-load assemblies.
