Value Collection BDNA--47329-3 M8 X 1.25 X 80 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION BDNA--47329-3 is a metric hex head cap screw designed for general-purpose fastening applications where corrosion resistance is required. Manufactured from 18-8 austenitic stainless steel meeting Grade A2 designation, it offers solid resistance to oxidation and mild chemical exposure. The fastener measures M8 x 1.25 thread pitch with an 80 mm length under head and is partially threaded per DIN 931 standards. The 13 mm hex drive size accommodates standard metric wrenches. This screw is installed by millwrights, pipefitters, maintenance technicians, and mechanical contractors working in metric-standard assemblies.

This hex head cap screw suits residential and commercial applications where stainless fasteners are specified for corrosion-prone environments, including HVAC equipment mounting, plumbing bracket assemblies, pump housings, and general mechanical fabrication. The DIN 931 partial thread profile makes it suitable for through-bolt applications where an unthreaded grip length under the head is needed for precise clamping. It is commonly used in food processing, marine-adjacent, and outdoor mechanical installations where standard carbon steel fasteners would corrode prematurely.

Key Features

• 18-8 austenitic stainless steel construction provides corrosion resistance in wet and mildly corrosive environments
• Grade A2 material designation meets DIN 931 standard for partially threaded metric hex head fasteners
• M8 x 1.25 thread pitch with 80 mm length under head for versatile through-bolt fitment
• 13 mm hex drive size compatible with standard metric open-end, box, and socket wrenches
• Partial threading along shank preserves grip length for load-bearing and shear-critical joints

Compatibility

Designed as a DIN 931 metric hex head cap screw for use in any M8 x 1.25 threaded application requiring an 18-8 stainless steel partially threaded fastener.

Installation Notes

Installation should be performed by qualified mechanical technicians following applicable fastener torque guidelines from the relevant equipment manufacturer or industry standard. De-energize or shut down any equipment before fastener replacement or service. Avoid mixing stainless steel fasteners with dissimilar metals in submerged or high-moisture environments to minimize galvanic corrosion risk. Use calibrated torque tools when specified by the equipment manufacturer.
