    Bit socket

    Posted by Paul Consani on Jun 21st 2020

    When traveling in my pelican case bits and sockets are used as much as possible to save tool case weight. This adapter makes all bits available to all drive ratchet handles and extenders. Great versatility. Good quality product.

    A must have!

    I use this adapter for my 3/8 torque wrench for mountain bike work, and it allows me to use any 1/4 inch hex drive bit like a dream. Bits never pull out of the adapter because of its locking feature. Another hit from Wera!

    The adapter adapts nicely. Holds the bits solidly. I look forward to using this quite a bit.

    High quality fairly low profile adapter. Bits are securely locked into place.
