Value Collection HC3X02520-050BX M2.5 Hex Cap Screw Din 933

Product Description

The VALUE COLLECTION HC3X02520-050BX is a metric hex head cap screw designed for general mechanical assembly and fastening applications. It features an M2.5 x 0.45 thread with a 20 mm length under the head and is fully threaded along its entire shank. Manufactured from 18-8 austenitic stainless steel to Grade A2, this fastener provides solid corrosion resistance for use in wet, humid, or chemically mild environments. The bright uncoated finish retains the natural appearance of the steel. A 5 mm hex drive size allows installation with standard metric hex tools. This screw conforms to DIN 933 dimensional standards and ships in a minimum order quantity of 50 pieces.

These small-diameter metric screws are well suited for precision mechanical assemblies, instrumentation panels, electronics enclosures, HVAC control boards, and light-duty plumbing or electrical fixtures where stainless steel fasteners are specified. The M2.5 thread size is common in equipment requiring fine-pitch fasteners with reliable clamp load in confined spaces. Technicians working on residential or light commercial equipment will find this size appropriate for securing brackets, covers, and terminal boards where corrosion resistance is required.

Installation Notes

Installation of small-diameter metric screws requires a correctly sized 5 mm hex wrench or socket to prevent rounding of the fastener head. Ensure mating threads are clean and free of debris before driving. Do not over-torque M2.5 fasteners, as the small thread form is susceptible to stripping in softer base materials. Always de-energize any electrical equipment before accessing fastened covers or panels.
