Value Collection MPZX04040-050BX M4x0.7 Pan Head Screw

Product Description

The VALUE COLLECTION MPZX04040-050BX is a metric machine screw designed for general-purpose fastening in mechanical, electrical, and light structural assemblies. It features an M4x0.7 thread, a pan head profile, and a Pozidriv drive recess sized at 2 mm. The fastener is manufactured from 18-8 stainless steel, also designated A2 under the ISO/DIN classification system, providing solid corrosion resistance in both indoor and outdoor environments. The bright, uncoated finish leaves the base material exposed with no additional plating. At 40 mm length under head, this screw suits medium-depth through-hole and tapped-hole applications. It conforms to DIN 7985 and ships in a minimum order quantity of 50 pieces.

This fastener is used wherever a metric M4 pan head screw is specified in equipment assembly, panel mounting, enclosure fabrication, or component attachment. The pan head profile provides a wide bearing surface that distributes clamping load across thin materials without requiring a washer. The Pozidriv recess delivers better torque transfer than a standard Phillips drive, reducing cam-out during powered or hand installation. Typical applications include electrical enclosures, HVAC control panel assembly, light equipment fabrication, and general sheet-metal or plastic fastening work. Installers across electrical, HVAC, and mechanical trades will encounter this thread size regularly in metric-spec equipment.

Key Features

• M4x0.7 thread, 40 mm length under head per DIN 7985 standard
• Pan head with 8 mm head diameter and 3.25 mm head height for broad clamping surface
• Pozidriv drive size 2 mm reduces cam-out compared to standard Phillips
• 18-8 stainless steel (A2) construction for corrosion resistance without plating
• Bright, uncoated finish — no additional coating to chip, flake, or interfere with grounding contact
• Shipped in multiples of 50 pieces to support volume service and assembly work

Compatibility

Designed as a general-purpose DIN 7985 metric machine screw suitable for any tapped or through-hole application specifying an M4x0.7 thread with a pan head Pozidriv drive.

Installation Notes

Use a size-2 Pozidriv screwdriver or bit — not a Phillips — to avoid drive damage and cam-out. Verify that the mating thread is M4x0.7 before installation; cross-threading stainless fasteners into aluminum or soft metal can cause galling, which is not reversible. Apply only hand-tight plus a fraction of a turn in thin or delicate materials unless a torque spec is called out in the equipment service documentation. In electrical enclosure work, confirm whether the fastener is intended to serve as a grounding path before substituting an uncoated stainless screw for a plated original.
