Value Collection MSCXX05040-050BX M5x0.8 Fillister Screw 50pk

Product Description

The VALUE COLLECTION MSCXX05040-050BX is a metric machine screw with a fillister head and slotted drive, manufactured from Grade 316 (A4) stainless steel with a bright, uncoated finish. Conforming to DIN 84, this fastener features an M5x0.8 thread size and a 40 mm length measured under the head. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it suitable for environments exposed to moisture, salt, or mild chemicals. Each box contains 50 pieces and is sold as a minimum order quantity of 50 units. These screws are installed by maintenance technicians, millwrights, HVAC service professionals, plumbers, and electricians working on equipment assemblies, panel mounting, and general mechanical fabrication.

This fastener is suited for metric applications requiring a fillister head profile, which provides a taller head height and deeper drive recess than a standard pan head, giving better torque transfer with a slotted screwdriver. Typical installations include electrical enclosures, equipment panels, plumbing fixture brackets, HVAC unit assemblies, and general stainless steel fabrication where corrosion resistance is required. The without-washer style and under-head length measurement make it straightforward to specify in metric assemblies following DIN standards.

Key Features

• M5x0.8 metric thread with 40 mm length under head per DIN 84 standard
• Fillister head profile delivers greater head height and deeper slotted recess for improved torque transfer
• Grade 316 (A4) stainless steel construction for strong corrosion resistance in wet or chemical-exposed environments
• Bright, uncoated finish — no coating to chip, flake, or introduce galvanic incompatibility
• No washer style — clean, direct bearing surface against mating material
• Sold in a 50-piece box suitable for service kits, maintenance stock, and assembly operations

Compatibility

Designed for metric threaded assemblies requiring an M5x0.8 DIN 84 fillister head screw in stainless steel. Suitable for use in any application where a Grade 316 A4 stainless metric fastener conforming to DIN 84 is specified.

Installation Notes

Install using a standard slotted screwdriver or bit sized to the head recess — an undersized driver will slip and damage the slot. Power down or de-energize any equipment panel before fastener work in electrical or HVAC enclosures. Do not mix with non-stainless fasteners in corrosive environments where galvanic coupling could accelerate degradation. Follow applicable equipment manufacturer torque recommendations for M5 metric fasteners; no specific torque value is supplied with this part.
