Value Collection HC3X20025-025BX Hex Cap Screw M20

Product Description

The VALUE COLLECTION HC3X20025-025BX is a metric hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from 18-8, 304 austenitic stainless steel (Grade A2), it offers reliable corrosion resistance in wet, chemical, or outdoor environments. The screw features an M20 x 2.50 mm thread size with a 25 mm length under the head and is fully threaded from tip to head. A 30 mm hex drive size accommodates standard wrenches. The uncoated, bright finish is compatible with a wide range of stainless hardware and gasketed assemblies. This fastener is appropriate for plumbers, mechanical contractors, pipefitters, and maintenance technicians working on corrosion-sensitive structural connections.

This hex head cap screw is suited for metric fastening in residential and commercial mechanical systems, structural steel assemblies, pipe flanges, equipment mounting, and similar applications where stainless steel hardware is specified. It conforms to DIN 933, EN 24017, and ISO 4017 standards, making it interchangeable with other metric fasteners built to those specifications. It is sold individually and is appropriate for low-quantity replacement or repair work.

Installation Notes

This fastener is installed by licensed mechanical contractors, pipefitters, or maintenance technicians using a standard metric wrench or socket sized to the 30 mm hex. De-energize and depressurize any system before servicing fastened connections. Use appropriate thread-locking compound or anti-seize on stainless fasteners where galling is a concern, as austenitic stainless steel is susceptible to galling under high torque without lubrication. Refer to applicable project specifications or engineering standards for required torque values.
