3/8" Friction Ring

$4.99

Fix Number: FIX11878410
Manufacturer Part Number: 44-90-1050

This is a metal friction ring, sold individually and used in impact wrenches as part of the anvil assembly. It measures roughly 3/8-Inches. When the socket is installed, the ring is compressed, and the tension that is created is what holds the socket securely in place. Over the lifetime of the tool, the ring can compress too small, and it will no longer fit properly in the socket, and will need to be replaced. For this repair you will need a pick to pry off the friction ring, a pair of needle nose pliers, retaining ring pliers, and a small screwdriver.

3/8" O-Ring

$4.99

Fix Number: FIX11877651
Manufacturer Part Number: 34-40-1885

This O-ring is attached to the anvil and backs up the tension ring. The O-ring minimizes how much the tension ring can compress when a socket is installed. O-rings are common wear parts that tend to harden and deteriorate over time due to their rubber material. A sign that this O-ring needs to be replaced is if the socket is no longer being held properly on the anvil. This manufacturer-approved part is sold individually.

This is an authentically sourced collet for rotary tools. This collet is for using bits with 1/8-Inch arbors. Over time and heavy use, the collet will wear and will require replacing. You may need a collet nut wrench (sold separately) to remove the collet nut.
