Value Collection MSFXX05055-050BX M5x0.8 Flat Head Screw 316 Ss

Product Description

The VALUE COLLECTION MSFXX05055-050BX is a metric flat head slotted machine screw manufactured from Grade 316 A4 stainless steel with a bright, uncoated finish. It carries an M5x0.8 thread size and an overall length of 55 millimeters. The DIN 963 standard governs the head geometry, ensuring consistent countersink seating across compatible hardware. Grade 316 stainless provides elevated corrosion resistance compared to Grade 304, making this fastener well suited for wet, marine, and chemical-exposure environments. Sold in a minimum order quantity of 50 pieces, these screws are used by millwrights, maintenance technicians, fabricators, and general mechanical tradespeople who need reliable metric fasteners for structural and equipment assembly work.

This fastener is appropriate for general mechanical assembly, panel mounting, equipment enclosures, and marine or outdoor installations where corrosion resistance is a priority. The flat head profile allows the screw to sit flush with or below the surface of countersunk material, making it a common choice in sheet metal work, instrument panels, and machinery guards. The slotted drive is compatible with standard flat-blade screwdrivers and can be driven manually or with power tools equipped with the appropriate bit. No washer is included or required by the DIN 963 specification for this head style.

Compatibility

Designed as a standard DIN 963 metric flat head slotted machine screw suitable for use in any application requiring an M5x0.8 thread pitch with a countersunk flat head and slotted drive.

Installation Notes

Installation is performed by millwrights, maintenance mechanics, or general tradespeople using a flat-blade screwdriver or matching slotted power bit. Countersink the mating material to the appropriate DIN 963 angle before driving to ensure a flush seating surface. Do not over-torque stainless steel fasteners, as galling can occur; apply an appropriate anti-seize compound when driving into stainless or aluminum components. Ensure the receiving thread is clean and free of debris before installation.
