Value Collection MSFXX03020-050BX M3x0.5 Flat Head Screw 50pk

Product Description

The VALUE COLLECTION MSFXX03020-050BX is a metric flat head slotted machine screw made from Grade 316 stainless steel with a bright uncoated finish. It features an M3x0.5 thread and a 20 mm overall length, conforming to DIN 963 dimensional standards. Grade 316 stainless provides strong corrosion resistance, making it suitable for wet, marine, and chemically exposed environments. These screws are sold in a minimum order quantity of 50 pieces per box, making them practical for production assembly, maintenance kits, and field service stockrooms. Installers and assemblers working with metric hardware in corrosive or outdoor applications will find this fastener a reliable choice.

This fastener is used wherever a low-profile countersunk head is required in a metric-threaded assembly. Common applications include HVAC equipment panels, electrical enclosures, plumbing fixture brackets, and pool equipment housings where flush mounting and corrosion resistance are priorities. The slotted drive is compatible with standard flat-blade screwdrivers. Grade 316 stainless is frequently specified in coastal, marine, and chemical plant environments due to its higher molybdenum content compared to Grade 304.

Key Features

• M3x0.5 metric thread with 20 mm overall length per DIN 963 standard
• Grade 316 A4 stainless steel construction for superior corrosion resistance
• Flat countersunk head profile for flush surface mounting
• Slotted drive compatible with standard flat-blade screwdrivers
• Bright uncoated finish — no additional coating to interfere with dimensional tolerances
• Sold in a box of 50 pieces to support production and maintenance quantities

Compatibility

Designed as a DIN 963 metric flat head slotted machine screw for use in M3-threaded assemblies requiring a countersunk seat and Grade 316 stainless material specification.

Installation Notes

Installation is performed with a flat-blade screwdriver sized to the slotted head. Ensure the mating material has a properly sized countersunk recess to seat the flat head flush. Avoid over-torquing stainless steel fasteners, as galling can occur — applying an appropriate anti-seize compound is a common field practice for stainless-to-stainless assemblies. Follow applicable equipment manufacturer torque guidance when reinstalling panels or structural components.
