Professional Applications & Engineering Value

These No. 10 x 1-1/4" black-oxide steel wood screws are engineered to address common challenges in wood fastening, such as splitting, corrosion, and installation inefficiency. The partially threaded configuration concentrates holding force near the head, reducing stress on the wood fibers and minimizing the risk of cracks in both hardwood and softwood applications. The flat head with 82° countersink ensures a clean, flush finish that enhances aesthetic appeal while preventing snagging. Made from durable black-oxide steel, these screws resist moisture and oxidation, making them suitable for indoor and mildly humid environments. The Phillips drive and pointed tip facilitate quick starts and smooth driving, streamlining assembly in furniture, cabinetry, and construction projects where precision and reliability are critical.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.19" and approximately 13 threads per inch, ensuring consistent fit and performance. The thread forming method and right-hand threading provide secure fastening without the need for additional tapping. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of hazardous substances, supporting environmental safety and regulatory requirements in industrial supply chains.
