Upgrade your assemblies with our Thread Rolling Screws — an unslotted, indented serrated, hex washer head fastener engineered for strength and reliability. Made from steel with a zinc finish and a waxed coating, these screws form their own threads as they drive, delivering a secure, vibration-resistant hold without pre-tapping.

• Drive: Tri-Lobe drive for secure, cam-out resistant installation.
• Head: Hex Washer Head with serrated under-face to resist loosening and distribute load.
• Threading: Thread Rolling (self-forming) threads that cut more efficiently and improve shear strength.
• Finish: Zinc-plated steel with a waxed coating for corrosion resistance and lubrication during installation.
• Format: Unslotted, indented serrations to grip surfaces and reduce pull-out.
• Size: 5/16-18 x 1-1/2 — standard coarse thread for many metal assemblies.

Applications: A robust screws alternative to Taptite screws in metal-to-metal or sheet metal projects. These screws are ideal for automotive, electrical enclosures, machinery, and cabinetry applications where a strong, fast, self-forming thread is essential.
