Value Collection 663166PS M6x1 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION 663166PS is a metric machine screw designed for general-purpose fastening in metal, plastic, and composite assemblies. It features an M6x1 thread with a 40mm overall length, a flat (countersunk) head, and a Phillips drive. The screw is manufactured from Grade 4.8 steel with a zinc finish for basic corrosion resistance. This fastener is installed by industrial maintenance technicians, millwrights, HVAC installers, and equipment assembly personnel wherever a flush-seating screw is required in a tapped or threaded hole.

This screw is suited for light-to-medium duty fastening applications in residential and commercial equipment assembly, panel mounting, and machinery maintenance. The flat head profile allows the fastener to sit flush with or below the surface of the mating material when installed in a countersunk hole. Conforming to DIN 965, it integrates with standard metric fastener specifications common in European and international equipment platforms.

Key Features

• M6x1 thread size with 40mm overall length for medium-reach countersunk fastening
• Flat (countersunk) head seats flush with surface when installed in a properly prepared countersink
• Phillips drive compatible with standard Phillips screwdrivers and power driver bits
• Grade 4.8 steel construction provides adequate tensile strength for general-purpose metric fastening
• Zinc finish offers basic corrosion protection in dry to mildly humid environments
• Conforms to DIN 965 fastener standard for dimensional consistency

Compatibility

Designed as a standard DIN 965 metric replacement or maintenance fastener for assemblies requiring an M6x1 flat head Phillips machine screw with a 40mm overall length.

Installation Notes

Installation should be performed by qualified maintenance or assembly personnel using an appropriate Phillips driver sized for the screw head. Ensure the mating component has a properly formed countersink angle to match the flat head profile before installation. Do not overtorque, as Grade 4.8 fasteners have defined tensile limits suited for general rather than structural applications. Confirm thread engagement depth in the receiving component meets applicable assembly specifications before final torque.
