Bulk Thread-Cutting Screws: High-Quality and Durable

Introducing our Bulk 1/4″-20 Unslotted Indent Hex-Washer Serrated Head Thread-Cutting Screws — Type F, which are perfect for demanding applications. These screws are designed for fast installation and vibration-proof clamping, making them ideal for use in trailer floors, steel framing, dock builds, and timber-to-steel assemblies. Crafted from heat-treated carbon steel, these screws offer high tensile and shear strength, ensuring a reliable and long-lasting performance.

Key Features and Benefits

Our Thread-Cutting Screws are not just durable; they are also packed with features that enhance their functionality. The bright zinc electro-plate finish and hydrogen-relief baking provide superior corrosion resistance, while the factory dry-waxing ensures consistently low seating torque. The radial serrations under the captive washer bite into steel or wood, preventing loosening due to vibration. Additionally, the Type F fluted point taps clean female threads in pre-drilled or punched holes, eliminating the need for a nut.

Specifications and Applications

These Thread-Cutting Screws come with a diameter of 1/4″-20 UNC and a Type F cutting point. They feature an unslotted indent hex-washer head style with a ⅜″ hex drive size. The bright-zinc finish is RoHS compliant and includes light oil, baked treatment, and factory wax-lubing for repeatable clamp load. This product is a great choice for OEM steel fabrication, trailer shops, and dock builders, offering a bulk packaging solution that is both convenient and efficient.
