Value Collection MSFX03014-050BX M3x0.5 Flat Head Slotted Screw

Product Description

The VALUE COLLECTION MSFX03014-050BX is an M3x0.5 flat head slotted machine screw manufactured from 18-8 stainless steel (A2 grade) with a bright, uncoated finish. Conforming to DIN 963, this fastener features a countersunk flat head profile and a single slotted drive. The overall length is 14 mm with a matching 14 mm length under the head, making the entire shank available for engagement. This package contains 50 screws and is sold as a single box. These fasteners are installed by electricians, HVAC technicians, plumbers, and general tradespeople wherever a corrosion-resistant metric fastener is required.

This screw is suited for light-duty fastening applications in residential and commercial settings where metric hardware is specified. The DIN 963 flat head profile allows the fastener to sit flush with or below the mating surface when installed in a properly countersunk hole. The 18-8 A2 stainless steel construction resists corrosion in damp or mildly corrosive environments, making it appropriate for use in mechanical enclosures, control panels, HVAC equipment assemblies, plumbing fixture brackets, and similar applications requiring a clean, low-profile fastener head.

Key Features

• M3x0.5 thread size with 14 mm overall length for precise metric fitment
• Flat countersunk head per DIN 963 for flush or sub-flush installation
• Slotted drive compatible with standard flat-blade screwdrivers
• 18-8 A2 stainless steel construction provides corrosion resistance without a surface coating
• Bright uncoated finish — no plating to crack, peel, or add dimensional variance
• Box of 50 screws minimizes reorder frequency for routine service work

Compatibility

Designed as an OEM-style and general-service replacement metric machine screw for applications specifying an M3x0.5 flat head slotted fastener conforming to DIN 963.

Installation Notes

Install using a flat-blade screwdriver sized to the slot width to avoid cam-out and head damage. A properly sized countersink in the mating material is required to achieve a flush seating surface per the DIN 963 head geometry. De-energize any electrical or mechanical equipment before replacing fasteners in live panels or assemblies per applicable NEC or equipment manufacturer guidelines. Do not over-torque stainless steel fasteners — galling can occur without lubrication on threads engaging stainless mating hardware.
