Value Collection HC3X18055-010BX M18 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION HC3X18055-010BX is a fully threaded hex head cap screw in the metric M18 x 2.50 thread size with a 55 mm length under head. Manufactured from 18-8 austenitic Grade A2 stainless steel, it carries inherent corrosion resistance suited to wet, outdoor, and chemically active environments. The bright, uncoated finish meets DIN 933 dimensional standards. A 27 mm hex drive across the flats allows standard wrench engagement. Technicians in plumbing, HVAC equipment assembly, pool equipment installation, and general mechanical work rely on this fastener class when corrosion resistance and metric thread compatibility are both required.

This screw is appropriate for general-purpose metric fastening applications across residential and light commercial installations. It suits structural and mechanical assemblies where stainless steel is specified to resist oxidation, chlorine exposure, or moisture contact. DIN 933 compliance means dimensional interchangeability with other conforming fasteners of the same thread and length, making it a reliable replacement or service fastener in metric-threaded equipment and panel assemblies common to HVAC, plumbing, and pool service work.

Compatibility

Designed as a DIN 933-compliant metric hex head cap screw for use in any assembly specifying an M18 x 2.50 fully threaded fastener in stainless steel.

Installation Notes

Installation should be performed by a qualified technician using an appropriately sized 27 mm wrench or socket. Power down or depressurize any equipment before accessing fastened assemblies. Torque to the value specified by the equipment manufacturer for the application and joint material — do not apply values from this product listing. Use of stainless fasteners in aluminum or dissimilar-metal assemblies may require anti-seize compound per applicable manufacturer guidance to prevent galling.
