Socket bit Torx 1/4" T40 x 37 mm, King Tony (KY203340)

King Tony Torx socket bit for 1/4" drive, size T40 and length 37 mm is a compact insert designed to work with 1/4" ratchets, bit holders and screwdrivers that accept a 1/4" hex drive. The bit provides a Torx T40 tip for reliable engagement with Torx-head fasteners and is intended for tasks that require controlled torque and precise alignment. Its 37 mm length balances reach and control for use in moderate-depth fastener locations.

Advantages

This Torx socket bit offers accurate tip geometry to reduce cam-out and wear on both fastener and tool. The 1/4" hex shank ensures compatibility with common compact drivers and bit holders, making it suitable for quick tool changes and use with extension adapters. Its 37 mm overall length provides better access than short bits while remaining manageable in tight spaces. Manufactured by a reputable tool brand, the bit is produced to standard dimensions for consistent fit with T40 fasteners.

Suitable for

• Automotive interior and trim fasteners that use Torx T40 heads
• Mechanical assembly and disassembly where a T40 tip is required
• General repair and maintenance tasks in workshops and home garages
• Use with 1/4" ratchets, bit holders, compact screwdrivers and torque drivers

Key specifications

• Drive size: 1/4" hex shank compatible with 1/4" tool holders
• Tip profile: Torx T40
• Overall length: 37 mm
• Material and heat treatment: manufactured to tool-grade hardness for wear resistance (manufacturer standard)

How to use

Insert the 1/4" hex shank into a compatible ratchet, bit holder or screwdriver. Align the Torx T40 tip with the fastener and apply steady torque while keeping the tool axis aligned with the fastener to minimize cam-out. For deeper or recessed fasteners, combine the bit with an appropriate extension or bit holder. Inspect the tip and fastener seat before applying high torque to ensure secure engagement.

Usage recommendations

Use the bit with tools rated for the required torque and avoid excessive force that may deform the Torx tip or fastener. Keep the bit clean and replace it when wear or rounding of the tip is visible to maintain safety and fastening accuracy.
