SPAX MDF & Finishing Trim Screws are the ideal choice for woodworking, carpentry, and detailed interior projects where clean finishes and precision fastening matter most. Engineered specifically for dense wood, hardwood, trim, MDF board, baseboards, door jambs, and cabinets, these high-performance screws deliver superior strength, holding power, and aesthetic results. The razor-sharp 4CUT point eliminates the need for pre-drilling, even in dense MDF or hardwoods. This design prevents splitting while allowing for faster, more efficient installation. SPAX's patented thread serrations reduce driving torque, making it easier on power tools and helping extend battery life. The mini flat head design with cutting ribs under the head allows flush or countersunk installation for a clean look. The low-profile trim head with cutting nibs allows the screw to countersink cleanly, creating a smooth, flush finish ideal for visible areas like cabinetry, trim molding, and fine furniture. The T-STAR plus drive system ensures a tight, slip-free connection with superior bit engagement—no stripping or cam-out. SPAX MDF screws are tested and recognized for use in untreated and above-ground pressure-treated lumber in interior dry or damp environments (AWPA UC1-UC2), offering exceptional versatility across indoor projects. From cabinet installation and furniture assembly to molding and millwork, SPAX trim screws are trusted by pros and DIYers alike for their performance, durability, and ease of use.
