Value Collection 656258PS M2.5x0.45 Flat Head Slotted Screw

Product Description

The VALUE COLLECTION 656258PS is a flat head slotted machine screw manufactured from steel with a zinc finish. It carries a Grade 4.8 material rating and conforms to DIN 963 and ISO 2009 fastener standards. The M2.5x0.45 thread size and 8 mm overall length make it a compact metric fastener suited for light-duty mechanical assemblies. Licensed trades and maintenance technicians use these screws where a flush or countersunk head profile is required. The slotted drive accepts a standard flat-blade screwdriver. Sold in multiples of 100 units per order.

This screw is used in general mechanical assembly and maintenance applications requiring a metric countersunk fastener. The flat head profile seats flush with or below the mating surface, making it appropriate for panels, brackets, enclosures, and light equipment where a protruding head is not acceptable. The zinc finish provides basic corrosion resistance for indoor and light-exposure environments. HVAC, electrical, and plumbing tradespeople commonly use fasteners of this type when servicing equipment panels and access covers.

• Grade 4.8 steel construction meets DIN 963 and ISO 2009 standards
• Zinc finish for basic corrosion resistance in indoor applications
• Sold in minimum quantities of 100 units per order

Compatibility

Designed as an OEM-style replacement or general-use metric fastener for equipment panels, light enclosures, and mechanical assemblies requiring an M2.5x0.45 flat head slotted screw conforming to DIN 963 or ISO 2009 standards.

Installation Notes

Install using a flat-blade screwdriver sized to the slot width to avoid cam-out and head damage. Ensure the mating material is countersunk to the correct angle to accept the flat head profile before driving the fastener. Do not overtighten Grade 4.8 fasteners in thin or soft mating materials, as the lower tensile rating compared to higher grades increases the risk of stripping. Follow applicable equipment manufacturer torque guidelines when available.
