Product Information

The difference between trim head screws and flat heads lies in the size of the head. Trim heads are made more like a finishing nail and work very well in that capacity. When you are screwing in a place where the screw head is best hidden, trim head screw with color matched finish will virtually disappear. Trim head screws are similar to flat head screws in both looks and design. They have a circular head that is intended to finish flush with the surface of the material being fastened. The heads are often formed with nibs to ensure a nicer countersunk finish when the hole was not predrilled.

The ‘hex washer’ head is an updated, more commonly used version of the hex head. It is characterised by an attached washer style flange under the head, creating a large surface connection area. It is sometimes used in combination drives, with phillips or slotted drives. Oval A screw is a type of fastener characterised by a helical ridge, also known as a male (or external) thread. Typically made of metal, screws fasten materials by digging in and wedging into them by turning, upon torque applied.It is the policy of GRK Fasteners Ltd. to provide top quality fasteners that require no predrilling, suitable for all applications and provide strength and finishing that customers and construction codes require. The driver recess on the trim head is the same size as the one on a flat head screw of a similar size. It’s only the surface of the head around the recess that is smaller. This allows for less screw to show, much like that finishing nail. And just like the tiny nail, trim head screws are very often used in trim applications, especially on outdoor products. The ‘oval trim’ head is the same as the regular ‘oval’ head, but with a smaller diameter and countersink. Round

Less screw can be a good thing or it can be annoying. If you are already a little clumsy at handling fasteners, a trim head screw is only going to give you the slip more often. Because the head is smaller, there is less to grip, although that is normally made up for with a well recessed driver. GRK’s Trim™ Head screws are an excellent choice for most fine carpentry applications, as well as window extension jambs and more. Our Trim™ Head screws have the smallest screw head available; with screw lengths from 1-1/4″ (30 mm) to 5″ (125 mm). Most material splitting is prevented because of the Trim™ Head screw’s exceptionally small head and the W-Cut thread design. Fin/Trim™ screws are also available in white Climatek™ coated finish to blend in with white wooden trim boards. Anyone who's ever driven a screw in knows how annoying cam-out is - when the bit slips out of the screw head as torque increases. It's not only frustrating, but it can also damage the screw head, preventing it from being driven in or out. The improved engagement of the star drive virtually eliminates cam-out and will pull wood components tightly together with ease. Hex heads allow greater torque to be applied, and are driven with the force working against the outside of the head, unlike other varieties, which are internally driven, They are commonly used for bolts.
