Value Collection MSTX08035-050BX M8x1.25 Truss Head Slotted Screw

Product Description

The VALUE COLLECTION MSTX08035-050BX is a metric machine screw with an M8x1.25 thread and a 35 mm length under head. It features a truss head profile and a slotted drive. The fastener is manufactured from 18-8 stainless steel with a bright, uncoated finish, meeting Grade A2 corrosion resistance standards. The truss head offers a wider, lower-profile bearing surface compared to a standard pan head, distributing clamp load across a larger area. This screw is suited for assembly applications where a flush or low-profile head is required and where resistance to moisture or mild corrosion is important. Machinists, millwrights, and maintenance technicians commonly install this fastener type.

This screw is appropriate for general-purpose metric fastening in industrial, mechanical, and maintenance applications. The M8x1.25 thread pitch is the standard coarse metric pitch for 8 mm diameter fasteners, making it compatible with a wide range of tapped holes, threaded inserts, and metric nuts. The stainless steel construction makes it suitable for indoor and outdoor assemblies where mild corrosion resistance is needed. It conforms to fastener standard NFE 27128. Sold in a minimum order quantity of 5 pieces.

Key Features

• M8x1.25 coarse metric thread, standard pitch for 8 mm fasteners
• 35 mm length under head for consistent thread engagement measurement
• Truss head profile provides a wide, low-profile bearing surface
• Slotted drive compatible with flat-blade screwdrivers and bit sets
• 18-8 stainless steel construction, Grade A2, for corrosion resistance
• Bright, uncoated finish — no plating to affect dimensional tolerances
• Conforms to fastener standard NFE 27128

Compatibility

Designed for use in M8x1.25 tapped holes, threaded metal inserts, and with standard metric M8 hex nuts. Suitable for general metric assembly applications conforming to NFE 27128 specifications.

Installation Notes

Install using a flat-blade screwdriver or slotted bit sized for an M8 truss head fastener. Verify that the mating threaded hole or nut is M8x1.25 before installation to avoid cross-threading. Apply appropriate thread torque per the assembly specification for 18-8 stainless steel fasteners, as stainless steel is susceptible to galling if driven too quickly. No power tools without torque limiting are recommended for stainless steel fasteners.
