Part of Hilka's premium Pro-Craft range, these socket-mounted bits are forged from fully heat-treated Chrome Vanadium steel and finished with an industrial satin chrome coating. Utilising an intelligent dual-drive interface, this lightweight 0.3kg set enables uniform torque delivery to prevent tip twisting and catastrophic stripping on specialised automotive and appliance assemblies.

• Dual-Drive Configuration - Intelligently splits sizes between 1/4" drive for tight clearances and 3/8" drive for demanding high-torque fasteners.
• Chrome Vanadium Core - Forged from high-grade Cr-V alloy steel and fully heat-treated to ensure the star teeth remain sharp and deformation-free under immense load.
• Industrial Satin Coating - Protective anti-glare finish shrugs off corrosive shop chemicals, motor oil, and grease while preventing rust buildup.
• Knurled Finger Bands - Each socket collar features a precision-machined knurled pattern, offering a secure fingertip grip for fast manual spinning before tightening.
• Tension Storage Rail - Mounted on a robust steel clip rail to keep the set securely contained in a tool chest or hung flat on a workbench pegboard.
• 1/4" Square Drive TX Bits (4 Items): T10, T15, T20, T25 - 3/8" (3 Items): T27, T30, T40
