The DEWALT DT7165-QZ Hex Bit Size 4 (25mm) is a professional-grade screwdriver accessory designed for high-torque fastening applications. Manufactured from shock-resistant tool steel, this bit offers exceptional durability and resistance to wear, even under demanding conditions. Its hardened core enhances strength and reduces the risk of breakage, making it ideal for repetitive tasks in construction, assembly, and maintenance. With a hexagonal socket size of 4 mm, it fits securely into standard bit holders and delivers precise engagement with hex screws, minimizing cam-out and ensuring consistent torque transfer.
