Product Information

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 ‘binding’ type is a commonly used screw head type. It is an ideal choice for electrical applications; beneath the head is a prominent undercut area providing space for wire connections. 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. The ‘oval undercut’ is ideal for shorter screw lengths which require longer thread grip and more shallow countersinking. Fillister

The ‘square’ head is a suitable choice for applications that require more torque. It is most often used for switch coverings Truss It is similar to ‘flat’ heads, but with no driving recess. The ‘round countersunk’ head is used for shorter screw lengths to provide a longer thread grip and more shallow countersinking. Round Washer The type of head that your screw has will greatly affect the performance of the fasteners in your application. What that means is you should pay attention to which type of screw or nut and bolt you use. Many are better for use with specific materials, others should be put to use in certain circumstances. One of the more common types of screw seen in a wide variety of applications are trim-head screws and this style provides some unique benefits to your project. Other fasteners are Hex Head Cap Screws and Hex Bolts. There are a variety of screw head types for different materials, and for different applications; screws are often used to fasten sheet metal, wood, and plastic. Binding/Binding Undercut The Flat 100+ uses a 100-degree angle instead of the standard 82-degree kind. It is an ideal choice for thinner materials that require a flatter head. Flat 100+ Undercut

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. If you need something even smaller, ask you fastener distributor about sourcing out a trim head line that uses a #1 square head instead of the minimum #2 that is generally used on flat head types. A star drive bit is included free with each box. We recommend you buy a few spares, especially if you are working on a big project.

Truss heads are characterized by a curved surface and an extra-wide top. They are often used to prevent tampering., having a lower profile than most round heads The ‘pan’ head is the most commonly used rounded-top screw head. It works well in a range of applications that require a flat-bottomed screw. Hex Washer

Microsites

To stainless, or not to stainless? That is the question. Stainless steel screws provide the most corrosion resistance and are typically required in coastal applications. For most other applications, stainless steel is an optional and expensive upgrade. 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 The ‘flat undercut’ is very similar to the standard 82-degree head, having the same angle, but a shorter head. This allows it to provide a longer thread on the same screw length. Flat 100+ With their tiny (6mm diameter) heads, Silva's stainless-steel finishing trim screws provide a neat, professional finish. They are suitable for a wide variety of exterior applications where a discreet screw head is preferred. The ‘oval trim’ head is the same as the regular ‘oval’ head, but with a smaller diameter and countersink. Round
