8 x 5/8 in. 100 ea. Zinc Pan Head Combo Drive Screws

These 8 x 5/8 in. Zinc Pan Head Combo Drive Screws are designed for applications where you need a strong, reliable fastening solution without the screw head sinking into the wood. The wide pan head provides a generous, flat bearing surface that distributes clamping pressure over a larger area, making these screws especially useful for woodworking, cabinetry, and hardware installation.

Pan Head for a Flat Bearing Surface

The non-countersunk pan head has a broad, flat underside that seats firmly against the work surface. This design is particularly useful for attaching adjustable cabinet hardware, including drawer slides, hinges, brackets, and other components where a flush or countersunk head is not desired.

The slightly domed top and chamfered sides give the pan head its familiar appearance while providing ample surface area for the square-drive recess. Because the head remains above the material rather than sinking into the wood, it is an excellent choice for applications requiring consistent hardware positioning and dependable clamping pressure.

Genuine Combo Drive

The square-drive recess provides a positive connection between the driver bit and screw. Unlike traditional slotted screws, the Combo Drive helps reduce cam-out and keeps the driver engaged during installation. This makes these screws particularly convenient for repetitive assembly work and cabinet installation.

The square-drive system was developed by Canadian toolmaker P. L. Robertson in the early 1900s as a way to improve screw-driving performance. Its positive engagement has made the Robertson Combo Drive a popular choice among woodworkers and builders.

Clear Zinc Finish

The clear zinc finish provides the familiar bright silver appearance while offering moderate protection against rust and corrosion. The zinc coating is electroplated directly onto the steel surface, providing a durable finish suitable for many indoor woodworking and general-purpose fastening applications.

Deep-Thread Design

The deep-thread design features a reduced-diameter shank that allows for a deeper thread profile. The single-lead thread advances the screw one pitch with each complete revolution, providing strong engagement in wood.

The deeper thread profile provides excellent resistance to pull-out and is commonly associated with Lo-Root® or production screw designs. This makes these screws a practical choice when dependable holding power is important.

Trivalent Zinc and RoHS Compliance

These zinc-plated screws use a trivalent zinc coating. The trivalent zinc process provides a durable finish while meeting RoHS compliance requirements, making these screws a dependable choice for a wide range of woodworking and general-purpose fastening applications.
