Value Collection 656048PS M6x1 Flat Slotted Machine Screw 20mm

Product Description

The VALUE COLLECTION 656048PS is a metric machine screw with a flat head and slotted drive, manufactured from Grade 4.8 steel with a zinc finish. Conforming to DIN 963 and ISO 2009 standards, this screw features an M6x1 thread size and an overall length of 20 millimeters. The zinc coating provides basic corrosion resistance for general-purpose fastening applications. Grade 4.8 indicates a medium carbon steel with a minimum tensile strength appropriate for non-critical structural and mechanical assemblies. This fastener is sold in minimum order quantities of 100 pieces and is a standard choice for maintenance, equipment assembly, and fabrication work across multiple trades.

This machine screw is suited for general mechanical and structural fastening in residential, commercial, and light industrial settings. It is commonly used to secure machine components, enclosures, brackets, and panels where a flush or countersunk head profile is required. The slotted drive accepts a standard flat-blade screwdriver, making it compatible with hand tools and power drivers used by millwrights, electricians, HVAC technicians, and general maintenance professionals. No washer is included or required under the head for standard installation.

Key Features

Compatibility

Designed as a standard DIN 963 and ISO 2009 metric machine screw for use in any application requiring an M6x1 flat head slotted fastener with a 20 millimeter overall length.

Installation Notes

Installation is performed with a flat-blade screwdriver or compatible power driver bit sized for the slot width. Ensure the mating hole is properly tapped or threaded to M6x1 specification before driving the screw. Do not exceed the torque rating appropriate for Grade 4.8 steel to avoid thread stripping or head damage. When installing in metal panels or enclosures, a countersunk pilot hole matching the flat head angle is recommended for a flush finish.
