The Duchy Fasteners 4.0mm Hexagonal Bit, with a 1/4 inch hexagonal drive and 100mm length, is precision-engineered for optimal performance in a range of fastening applications. Manufactured from high-grade steel for exceptional durability, it maintains its precision tip longer than standard bits commonly available from Screwfix, Toolstation, or Orbital Fasteners. The 100mm length provides enhanced accessibility to deeply recessed fasteners, making it perfect for various professional tasks in automotive, carpentry, cabinetry, and construction. Its exact hexagonal shape ensures a secure grip in screw heads, significantly reducing the likelihood of slippage and rounding off fastener edges. This hexagonal bit is especially useful for precise jobs requiring accuracy and consistent torque. With Duchy Fasteners, you benefit from increased durability, precision craftsmanship, and superior quality, ensuring reliable results in every project you undertake.
