Value Collection MSFX03020-050BX M3x0.5 Flat Slotted Screw 50pk

Product Description

The VALUE COLLECTION MSFX03020-050BX is a metric flat head slotted machine screw manufactured from grade 18-8 stainless steel with a bright, uncoated finish. Sized at M3x0.5 with a 20 mm overall length, this fastener conforms to DIN 963 standards for flat head slotted screws. The countersunk head profile sits flush with or below the mating surface when installed, making it well suited for assemblies where a smooth, low-profile finish is required. Sold in a box of 50, these screws are a practical stock choice for maintenance shops, manufacturing lines, and field service kits that require a consistent, corrosion-resistant metric fastener.

These screws are used in light mechanical assemblies, enclosure fabrication, instrumentation mounting, and general equipment maintenance where metric fasteners and flush head profiles are specified. The stainless steel construction and uncoated finish make them appropriate for indoor and mildly corrosive environments. Technicians working on HVAC control panels, electrical enclosures, pump housings, and similar equipment will find this size a common fitment for M3-threaded bosses and clearance holes.

Compatibility

Designed for use in any application requiring a DIN 963 compliant M3x0.5 flat head slotted machine screw with a 20 mm overall length and no washer face.

Installation Notes

Install using a flat-blade screwdriver sized to the M3 slotted drive to avoid cam-out and head damage. Ensure the mating hole is properly countersunk to the DIN 963 included angle before installation. Do not overtighten stainless steel fasteners into stainless or aluminum threads, as galling can occur — apply an appropriate anti-seize compound when threading into similar alloys. Torque to the value specified by the assembly drawing or equipment service manual.
