Value Collection MSCXX05030-050BX M5x0.8 Slotted Machine Screw

Product Description

The VALUE COLLECTION MSCXX05030-050BX is a metric machine screw with a fillister head and slotted drive, manufactured to DIN 84 standards. It features an M5x0.8 thread and a 30 mm length measured under the head. The screw is made from Grade 316 stainless steel, also designated A4, which provides strong resistance to corrosion and chemical exposure. The bright, uncoated finish retains the natural appearance of the base material. This fastener is suited for precision assembly applications where a raised cylindrical head profile and tool-slot drive are required. Installation is performed by mechanical assemblers, maintenance technicians, and trade professionals working in corrosive or marine-adjacent environments.

This screw is appropriate for light to medium fastening tasks in residential, commercial, and industrial settings where stainless steel hardware is specified. The DIN 84 fillister head profile provides a larger bearing surface than a pan head while maintaining a relatively low overall height, making it useful in recessed clearance holes and close-tolerance assemblies. Applications include equipment enclosures, plumbing fixtures, pool and spa equipment, and electrical panel components where metric fasteners are required and corrosion resistance is critical.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• A4 material designation per DIN and ISO stainless fastener standards
• DIN 84 fillister head geometry for use in recessed or close-clearance holes
• Slotted drive compatible with standard flat-blade screwdrivers and power tools
• M5x0.8 metric thread, 30 mm length under head
• Bright, uncoated finish — no surface treatment to compromise dimensional tolerances

Compatibility

Designed as a standard DIN 84 metric machine screw for use wherever an M5x0.8 fillister head slotted fastener is specified in metric assemblies and equipment.

Installation Notes

Installation is typically performed by hand or with a flat-blade screwdriver or slotted bit driver; avoid over-torquing stainless steel fasteners, as galling can occur without proper lubrication. Ensure the mating thread or tapped hole matches the M5x0.8 thread pitch before driving. When used in electrical or plumbing assemblies, de-energize circuits and shut off fluid supply before service. Follow applicable codes and equipment manufacturer guidelines for fastener specifications.
