Screwdriver bit King Tony 102535S1 — slotted 3.5 mm, replacement bit

King Tony 102535S1 is a slotted replacement screwdriver bit with a 3.5 mm flat blade designed for use in bit holders, multi-bit drivers and compact tool sets. With a 25 mm total length and a precision-machined slotted tip, this lightweight 5 g bit offers accurate engagement with slotted screws used in general repair, electronics and assembly work where a 3.5 mm flat tip is required.

Advantages

The bit is manufactured from silicon chrome vanadium alloy steel (S2) and has been sand-blasted and oiled to resist corrosion. Its conforming geometry to the slotted profile ensures stable contact and reduced cam-out during use. The compact 25 mm length makes it suitable for tight or recessed screw access, while the low weight makes it convenient as a spare or replacement in portable tool kits.

Suitable for

• General household repairs and maintenance
• Electronics assembly and small device servicing
• Furniture assembly and light mechanical work
• Use in bit holders, multi-bit drivers and pocket tool kits

Key specifications

• Drive type: slotted (flat) tip
• Tip width: 3.5 mm
• Total length: 25 mm
• Material: silicon chrome vanadium alloy steel (S2)

How to use

Insert the 3.5 mm slotted bit into a compatible 1/4" hex bit holder or multi-bit driver until it seats securely. Select the appropriate hand or powered driver speed and apply steady axial pressure while turning to engage the screw head. For slotted screws, maintain alignment between the bit blade and screw slot to minimize cam-out and wear. Remove and inspect the bit after heavy use and replace if the tip becomes deformed or rounded.

Usage recommendations

Use the bit with correct-size slotted screws to ensure proper contact and reduce wear. Avoid excessive torque on small screws and use hand control when working with delicate electronics. Clean and lightly re-oil the bit after exposure to moisture to maintain corrosion resistance.
