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.

Truss heads are very useful for sheet metal work, insulation, and cabinetry-- an ideal choice for applications that require large holes, as the wide head prevents the screw from going through the hole. 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.

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+ They are self-tapping eliminating pre-drilling featuring the W-Cut™ threads for reduced torque, and our Climatek™ AC257 code approved coating. They are ESR code approved under ICC Report ESR-3201. ADVANTAGES

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 ‘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 ‘square’ head is a suitable choice for applications that require more torque. It is most often used for switch coverings Truss The Flat Undercut is used instead of the standard flat head for some short sizes. The 100-degree kind enables more shallow countersinking than standard 82-degree flat heads. Hex 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.

The round washer is a screw head which provides a larger bearing surface in applications where a round head is preferred. It is quite similar to the Modified Truss head style. Square (Set Screw) 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. 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. 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. The ‘oval undercut’ is ideal for shorter screw lengths which require longer thread grip and more shallow countersinking. FillisterThe ‘trim’ screw head is a standard countersunk screw that provides a flat, smooth surface after installation. It is an alternative to flat head screws, with a narrower head a more suitable choice for certain applications. The Flat Trim is often used as a finishing screw for carpentry and woodworking. Oval Undercut There are a wide variety of hidden fastener systems available. We’ve put together an infographic to help you decide which system is best for your application. 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. A smaller diameter, in addition to a higher profile, than round or pan heads, makes the ‘fillister’ screw head effective for a deeper slot. Flat Fillister 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 ‘oval trim’ head is the same as the regular ‘oval’ head, but with a smaller diameter and countersink. Round 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 Whether you are a professional or a do-it-yourselfer, you need a screw that is fast and easy to install, and most importantly, is reliable. Silva's star drive stainless steel finishing trim screws drive effortlessly into most wood types and are guaranteed to reduce the installation time on any project significantly. By saving you time, they'll be saving you money! 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.GRK is not responsible for product failure caused by the improper use or installation of its own or other building materials.

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. 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. The ‘round’ head is less commonly used these days, but it offers a round-surfaced alternative to other screw heads.
