Value Collection MSCXX08100-025BX M8x1.25 Fillister Screw

Product Description

The VALUE COLLECTION MSCXX08100-025BX is a metric machine screw with a fillister head and slotted drive, manufactured from Grade 316 A4 stainless steel with a bright, uncoated finish. The fillister head profile sits higher than a pan head, providing a deeper slot for increased driver engagement and a smaller footprint on the mating surface. At M8x1.25 threading and 100 mm length measured under the head, this fastener is suited for medium-to-heavy clamping applications where corrosion resistance is critical. Grade 316 stainless steel offers superior resistance to chlorides and harsh chemicals compared to Grade 304, making it a preferred choice in demanding service environments.

This screw is used in mechanical assemblies, equipment fabrication, and maintenance applications where a metric fastener with reliable corrosion resistance is required. The slotted drive is compatible with standard flat-blade screwdrivers and is commonly found in panel assemblies, pump housings, marine equipment, and process piping hardware. Installation is performed without a washer, as this part ships in the without-washer configuration. Trade professionals in HVAC, plumbing, electrical, and industrial maintenance will encounter this fastener in both new construction and retrofit work.

Key Features

• Grade 316 A4 stainless steel construction for superior chloride and chemical corrosion resistance
• M8x1.25 metric thread for compatibility with standard metric tapped holes
• 100 mm length under head for deep clamping reach in thick assemblies
• Fillister head profile provides a deep slotted recess for positive driver engagement
• Bright, uncoated finish maintains dimensional integrity without added coating thickness
• No washer included or required — designed for direct bearing surface contact

Compatibility

Designed for use in metric-threaded assemblies requiring M8x1.25 fasteners. Suitable for applications specifying Grade 316 A4 stainless steel hardware per ISO 3506 material standards.

Installation Notes

Installation requires a flat-blade screwdriver or slotted bit sized for an M8 fillister head screw. Verify that the mating tapped hole is clean, free of debris, and cut to M8x1.25 before threading. Apply appropriate anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. Do not over-torque — stainless steel fasteners are susceptible to thread galling if driven beyond recommended load limits without lubrication.
