Value Collection MSCXX04020-050BX M4x0.7 Fillister Screw 50pk

Product Description

The VALUE COLLECTION MSCXX04020-050BX is a metric machine screw with a fillister head and slotted drive, manufactured from Grade 316 stainless steel (A4) to DIN 84 standards. The fillister head profile offers a taller, narrower head than a pan head, providing a deeper slot engagement for secure torque transfer with a standard flat-blade screwdriver. Grade 316 A4 stainless steel delivers strong resistance to corrosion and chemical exposure, making this fastener well-suited for demanding environments. Thread size is M4x0.7 with a length under head of 20 millimeters. This package contains 50 screws with a bright, uncoated finish.

These fillister head machine screws are used in a wide range of mechanical assembly, enclosure fabrication, and equipment maintenance applications across industries including HVAC, plumbing, electrical, and general trade work. The M4x0.7 metric thread is a standard size found in panel assemblies, junction boxes, equipment housings, and instrument mounting. The bright uncoated finish is appropriate for indoor applications and environments where the corrosion resistance of the base alloy is sufficient without additional plating.

Key Features

• Grade 316 A4 stainless steel construction for strong corrosion resistance
• Fillister head profile with slotted drive for deep, positive blade engagement
• M4x0.7 metric thread per DIN 84 standard
• 20 millimeter length under head for precise fitment in metric-dimensioned assemblies
• Bright, uncoated finish — no coating thickness to account for in close-tolerance applications
• Sold in a pack of 50 to support job-site and bench-stock quantities

Compatibility

Designed as a standard DIN 84 metric machine screw for use in any M4x0.7 threaded hole or with a matching M4 nut in mechanical assembly, enclosure, or equipment applications requiring a fillister head slotted fastener.

Installation Notes

Installation requires a flat-blade screwdriver sized to fit the DIN 84 slotted head recess. Verify that the mating thread is M4x0.7 metric before installation. When fastening into stainless steel threaded holes or nuts, apply an anti-seize compound to reduce the risk of galling, which is common with austenitic stainless fasteners. Do not overtighten — follow the assembly specification for the equipment being serviced.
