FASTENMASTER Trim Screw 2″ L
The FASTENMASTER Trim Screw 2″ L features a low-profile trim head designed to minimize the screw footprint and reduce the risk of splitting PVC trim boards. A star-drive design minimizes cam-out, protecting both the fastener and bit during installation. The kit includes 75 screws, plugs, and setting tools, offering a streamlined solution for concealing fasteners in PVC trim projects.
Hard-to-Find Fastener Composite Trim Screws #8 x 1-5/8″
These composite trim screws offer a practical balance between diameter and length for PVC trim applications. The listed dimensions are #8 diameter with a length of 1-5/8 inch, crafted from steel for durability. They are suitable for finishing trim where a clean appearance is important, though corrosion resistance depends on environment and coating chosen.
FM FastenMon Composite Trim Screws, #8 x 1-1/2”
These stainless steel trim screws from FM FastenMon are rated 304 stainless steel, providing excellent rust and corrosion resistance. The hidden finish feature helps the screw head disappear into the surface, making them ideal for PVC, composite boards, and exterior trim. They use a T-10 star drive for user-friendly installation with reduced risk of slipping or stripping.
GRK White 8 x 2 Composite Screws
GRK composite screws are designed to attach PVC and cellular PVC securely, with a white finish for an aesthetically pleasing look. The underhead reverse thread helps reduce mushrooming while delivering a secure hold in PVC trim and composite panels. The white finish also helps blend the screw with light-colored PVC surfaces.
Pro Plug System Stainless Steel Screws for PVC
Starborn Pro Plug System stainless steel screws are sized #10 x 2-1/2” with a star drive. They are made from Type 305 stainless steel for corrosion resistance and outdoor durability, suitable for Pro Plug PVC system installations. The system integrates with matching plugs for a concealed, finished appearance across outdoor PVC projects.
Buying Guide
Key considerations help determine the best screw choice for PVC projects. Material and environment are crucial; stainless steel offers superior corrosion resistance in coastal or humid areas, while coated carbon steel may suffice in dry, interior installations. Head design matters for a clean finish—low-profile or hidden-head styles minimize visibility on PVC trim. Drive type impacts installation ease and resistance to cam-out, with star-drive and T-10 star drives common in PVC fasteners. Length should align with board thickness to avoid protrusion or mushrooming. For concealed fasteners, consider systems that pair screws with matching plugs.
Durability and finish are also important. For outdoor use, select corrosion-resistant materials such as 304 stainless steel or painted/coated options designed for PVC. Compatibility with PVC and composite boards minimizes cracking and splitting during fastening. If you plan coastal or salt exposure, stainless steel options typically perform best. Finally, price and availability influence choice; a complete kit with plugs or a compatible drive bit can simplify installation and deliver a more uniform finished look.
