Quick Change Retainer Spring - Auto Body File Holder Accessory

A quick change retainer spring secures air hammer chisel bits and attachments in the tool shank, preventing them from flying out during use. The quick-release lever allows fast bit changes without additional tools.

This retaining spring is designed for the .401 Parker shank, which is the standard shank size on most professional air hammers, air chisels, and pneumatic body hammers.

The .401 Parker shank is an industry-standard size. This retainer spring fits all air hammers using the .401 shank, regardless of brand, making it a universal replacement.

Compress the old retainer spring and slide it off the shank, then press the new spring over the tool chuck. The one-piece high-tensile design snaps securely into position without special tools.

Yes. This retainer spring has a rust-resistant finish for extended service life in shop environments where moisture, coolant, and chemicals are present.

Replace the retainer spring when you notice bits loosening during use, the spring shows visible wear or damage, or the quick-release lever no longer functions smoothly.
