RENNSTEIG Splintentreiber with Sleeve, 2.8 mm (model R457 028 5)

RENNSTEIG Splintentreiber with Sleeve, 2.8 mm is a hand tool engineered for driving and removing split pins (cotter pins) in mechanical assemblies. The tool features a 2.8 mm diameter working tip and an integrated sleeve that helps centre the pin and guide force transfer for accurate alignment. It is designed for maintenance, repair, and assembly tasks where controlled impact and precise positioning are required.

Advantages

The integrated sleeve stabilizes the driver on the pin to reduce slippage and improve strike accuracy. A robust hardened tip provides consistent performance when installing or extracting split pins and resists deformation under repeated impacts. The tool’s ergonomic length and balanced weight distribution facilitate controlled force transmission, making it suitable for confined or hard-to-reach locations. The simple, single-piece working end minimizes the risk of burrs or catching on surrounding parts.

Suitable for

• Automotive maintenance and pin replacement
• Electrical panel and connector assembly or disassembly
• General workshop assembly and mechanical repairs
• Hobby and small-scale metalworking tasks requiring pin alignment

Key specifications

• Working tip diameter: 2.8 mm
• Integrated guiding sleeve for centred striking
• Hardened tip material for impact resistance
• Hand tool format suitable for use with hammer blows
• Length and balance designed for controlled force transmission

How to use

Select the driver with a working tip that matches the split pin diameter. Place the guiding sleeve over the exposed end of the split pin so the tip centres on the pin head. Hold the tool perpendicular to the pin and apply controlled hammer strikes to drive the pin into position or to extract it by reversing the process. Verify pin seating and alignment after installation, and avoid lateral forces that could bend the pin or tip.

Usage recommendations

Use safety glasses and appropriate hand protection when striking with a hammer. Inspect the driver tip before use for wear or damage; replace the tool if the tip is mushroomed or excessively worn. For repeated heavy-duty use, pair the driver with a support sleeve or backing plate to protect surrounding components and ensure consistent pin seating.
