Value Collection MSCX03020-050BX M3x0.5 Fillister Screw 50pk

Product Description

The VALUE COLLECTION MSCX03020-050BX is a metric machine screw with a fillister head and slotted drive, sold in a box of 50. It is manufactured from 18-8 stainless steel (A2 grade) with a bright, uncoated finish and conforms to DIN 84 standards. The M3x0.5 thread size and 20 mm length under head make this screw a common choice for light-duty fastening applications in equipment assemblies, panels, and enclosures. Machinists, maintenance technicians, and industrial assembly workers typically specify this fastener where corrosion resistance and a low-profile head are required.

This screw is suited for metric fastening applications in residential and commercial equipment, electronics enclosures, instrumentation panels, and general fabrication. The fillister head profile provides a greater bearing surface and deeper slot depth than a standard pan head, improving torque transfer with a flat-blade driver. The DIN 84 standard ensures dimensional consistency for applications requiring interchangeable metric hardware across assemblies and repair work.

Key Features

• M3x0.5 metric thread with 20 mm length under head per DIN 84 standard
• Fillister head design offers increased slot depth for better driver engagement
• 18-8 stainless steel (A2 grade) provides corrosion resistance in moist or chemical environments
• Bright, uncoated finish maintains base material properties without plating
• Slotted drive compatible with standard flat-blade screwdrivers
• Sold in a box of 50 for bench stock and production use

Compatibility

Designed as a DIN 84 metric machine screw for use in any application requiring an M3x0.5 fillister head slotted fastener in stainless steel.

Installation Notes

Installation is performed by hand or with a flat-blade screwdriver sized to the slot. Avoid power-driving stainless steel fasteners without proper speed control, as galling can occur and seize the fastener in the mating thread. Ensure the mating thread or nut is also stainless steel or a compatible material to prevent galvanic corrosion. Follow applicable equipment manufacturer torque guidance when assembling precision components.
