Screwdriver bit King Tony 203730 — Torx T30H, 37 mm, 1 pc

King Tony 203730 is a single Torx screwdriver bit with a T30H tip profile and a length of 37 mm. Manufactured by King Tony for replaceable-bit screwdrivers and bit drivers, this 1-piece bit is intended for secure engagement with tamper‑resistant Torx fasteners used in assembly, repair and maintenance tasks. The bit is made from silicon alloy steel (S2), polished and chrome plated to resist wear and facilitate handling during repeated use.

Advantages

The S2 silicon alloy steel construction provides high toughness and resistance to deformation under torque. Polished chrome plating reduces corrosion and makes the bit easier to insert and remove from bit holders. The T30H profile offers a hardened engagement geometry for tamper‑resistant Torx screws, improving contact stability and minimizing cam‑out during fastening operations.

Suitable for

• Assembly of mechanical components that use Torx T30H fasteners
• Repair and maintenance of electronic enclosures and equipment with tamper‑resistant Torx screws
• Automotive and industrial tasks requiring a compact 37 mm bit
• Use with bit drivers, ratchet adapters and compatible screwdriver handles

How to use

Insert the King Tony T30H bit into a compatible bit holder, screwdriver handle or ratchet adapter. Align the Torx tip with the tamper‑resistant screw head and apply steady axial pressure while turning the driver to fasten or loosen the screw. Use appropriate torque settings on powered drivers to avoid over‑tightening and verify fit before applying high torque. After use, store the bit in a bit organizer or tool case to protect the tip profile and plating.

Usage recommendations

For best results, match the T30H bit to tamper‑resistant Torx fasteners of the correct size and avoid using worn or damaged bits. When working with power drivers, use controlled torque settings and short bursts to reduce heat and wear on the bit and fastener. Periodically inspect the bit for rounding or corrosion and replace when tip geometry degrades.
