Value Collection CA6X08020-050BX Carriage Bolt M8 X 1.25

Product Description

The VALUE COLLECTION CA6X08020-050BX is a metric carriage bolt designed for use in structural and mechanical fastening applications where corrosion resistance is required. This bolt features an M8 x 1.25 thread with a 20 mm length under head and a square neck that locks the fastener in place when drawn through a mating hole, preventing rotation during tightening. The body is manufactured from Austenitic Grade A2 stainless steel, which provides strong resistance to oxidation and common corrosives, making it suitable for both indoor and outdoor installations. Machinists, millwrights, and assembly technicians working in corrosive or washdown environments will find this fastener well matched to their requirements.

This carriage bolt is sized for metric applications and conforms to DIN 603 standards, which define the round-head square-neck carriage bolt geometry common in European and globally specified assemblies. It is used in wood-to-metal connections, frame fabrication, equipment mounting, and general structural assembly where a flush or low-profile head presentation on one face is needed. The minimum order quantity is 50 pieces, making this part appropriate for job-lot procurement by facilities maintenance crews, fabrication shops, or contractors stocking metric hardware.

Key Features

• M8 x 1.25 metric thread with 20 mm length under head per DIN 603
• Square neck resists rotation during installation without requiring wrench access to the head
• Austenitic Grade A2 stainless steel construction for corrosion resistance in wet or outdoor environments
• Conforms to DIN 603 fastener standard for consistent dimensional interchangeability
• Sold in multiples of 50, suitable for bulk job or shop stock procurement

Compatibility

Designed as a metric DIN 603 carriage bolt for use in applications requiring an M8 x 1.25 thread pitch and a 20 mm under-head length in stainless steel construction.

Installation Notes

Carriage bolts are typically installed by machinists, maintenance technicians, or general tradespeople using standard metric wrenches or sockets on the nut side. Before installation, confirm the mating hole diameter is sized to allow the square neck to seat and lock without spinning. Torque should be applied to the nut only, as the head is not wrench-driven. Always verify material compatibility when installing stainless fasteners into dissimilar metals to manage the risk of galvanic corrosion in wet environments.
