Value Collection 656550PS M5x0.8 Flat Head Slotted Screw 50mm

Product Description

The VALUE COLLECTION 656550PS is a metric flat head slotted machine screw designed for general-purpose fastening in metal and fabricated assemblies. Built to Grade 4.8 steel with a zinc finish, it meets DIN 963 and ISO 2009 standards for dimensional accuracy and mechanical performance. The flat head profile sits flush with or below the surface of the mating material, making it well-suited for applications where a low-profile fastener is required. This screw is sold in a minimum order quantity of 100 pieces and is installed by machinists, millwrights, maintenance technicians, and general trade professionals working in light to medium-duty metal assembly.

This fastener is used in metric-threaded applications across industrial equipment, enclosures, fixtures, and structural assemblies where a flush-seating drive screw is specified. The M5x0.8 thread pitch is a standard metric coarse thread, compatible with tapped holes and threaded inserts machined to ISO metric standards. The 50mm overall length provides adequate engagement depth for medium-thickness material stacks. The zinc coating offers basic corrosion resistance suitable for indoor and protected environments.

Key Features

• Flat head profile seats flush with mating surface per DIN 963 and ISO 2009 standards
• M5x0.8 metric coarse thread for use in standard ISO-tapped holes and inserts
• 50mm overall length for medium-depth fastening applications
• Grade 4.8 steel construction provides reliable tensile and proof load performance for light to medium-duty use
• Zinc finish offers basic corrosion protection in dry or protected indoor environments
• Slotted drive accepts standard flat-blade screwdrivers and power driver bits

Compatibility

Designed as a general-purpose metric machine screw for use in any M5x0.8 tapped hole or threaded insert conforming to ISO metric coarse thread standards.

Installation Notes

Installation requires a flat-blade screwdriver or slotted driver bit sized to fit the M5 head recess. Ensure the mating hole is tapped to M5x0.8 ISO metric coarse thread specification before installation. Apply appropriate thread engagement depth per assembly drawing requirements. Do not overtorque, as Grade 4.8 fasteners are not rated for high-torque or structural load applications.
