Value Collection 656022PS M5x0.8 Flat Head Slotted Screw 20mm

Product Description

The VALUE COLLECTION 656022PS is a metric flat head slotted machine screw designed for general mechanical fastening applications. Manufactured from Grade 4.8 steel with a zinc finish for basic corrosion resistance, this screw conforms to DIN 963 and ISO 2009 standards, ensuring dimensional consistency and interchangeability with other metric hardware. The M5x0.8 thread pitch and 20 mm overall length make it suited to medium-duty panel, bracket, and housing assemblies where a flush-seating countersunk head is required. Installation requires a standard flat-blade screwdriver sized for an M5 slot drive. Sold in minimum order quantities of 100 pieces.

This fastener is used across a wide range of trade and industrial applications including HVAC cabinet assembly, electrical enclosure fabrication, plumbing fixture mounting, and general sheet metal or machined-part joining. The flat countersunk head sits flush with the mating surface when installed in a properly chamfered or countersunk hole, making it appropriate where protrusion clearance is a concern. No washer is included or required by the standard for this configuration.

Key Features

• M5x0.8 metric thread, 20 mm overall length for consistent dimensional fit
• Flat countersunk head profile seats flush with mating surface
• Slotted drive accepts standard flat-blade screwdrivers
• Grade 4.8 steel construction provides adequate tensile strength for light-to-medium duty fastening
• Zinc finish offers basic corrosion protection in dry indoor environments
• Conforms to DIN 963 and ISO 2009 standards for metric fastener interchangeability

Compatibility

Designed as a standard metric replacement or service fastener compatible with any application calling for an M5x0.8 flat head slotted machine screw per DIN 963 or ISO 2009 specifications.

Installation Notes

Installation is performed with a flat-blade screwdriver matched to the M5 slot width. The mating component should have a properly countersunk or chamfered hole to achieve a flush seating surface. Avoid over-torquing Grade 4.8 fasteners, as this grade has lower proof load than higher-grade metric hardware. Zinc-finished fasteners are not rated for outdoor or high-humidity environments without additional protective measures.
