Value Collection MSTX05050-050BX M5x0.8 Truss Head Screw 50mm

Product Description

The VALUE COLLECTION MSTX05050-050BX is a metric machine screw with a truss head profile and slotted drive, manufactured from 18-8 stainless steel (A2 grade) with a bright, uncoated finish. The truss head features a wider, lower-profile dome compared to a standard pan head, distributing clamping load over a broader bearing surface. The M5x0.8 thread pitch and 50 mm length under head make this fastener well-suited to general-purpose mechanical assembly where corrosion resistance and a clean appearance are required. Conforms to fastener standard NFE 27128. Sold in a minimum order quantity of 50 pieces.

This screw is used in light to medium-duty assembly applications across manufacturing, HVAC equipment fabrication, electrical enclosure work, and general mechanical maintenance. The 18-8 stainless steel construction provides good resistance to corrosion and oxidation in both indoor and mildly corrosive outdoor environments. The slotted drive is compatible with standard flat-blade screwdrivers and slotted power bits. The truss head profile is particularly useful where a large bearing area is needed without a washer or where countersinking is not practical.

Key Features

• M5x0.8 metric thread with 50 mm length under head
• Truss head provides wide bearing surface without a separate washer
• Slotted drive accepts standard flat-blade screwdrivers and power bits
• 18-8 (A2) stainless steel for corrosion resistance in general-service environments
• Bright, uncoated finish — no plating to introduce dimensional variation
• Conforms to NFE 27128 fastener standard

Compatibility

Designed as a general-purpose M5x0.8 metric machine screw suitable for tapped holes or with a mating nut in standard mechanical and electrical assembly applications conforming to NFE 27128.

Installation Notes

Installation is performed with a flat-blade screwdriver or matching slotted power bit sized for M5 fasteners. Verify that the mating thread or nut is clean and free of debris before driving. Apply appropriate thread engagement depth per the assembly specification — do not overdrive, as stainless fasteners are susceptible to galling if driven at excessive speed without lubrication. Always torque to the assembly drawing specification for the joint material and fastener grade.
