7-piece socket adapter and U-joint set

This Powerbuilt 640859 set bundles four drive-size adapters and three universal joints covering 1/4, 3/8 and 1/2 inch drives. Chrome vanadium steel construction meets or exceeds ANSI standards for professional automotive and industrial use.

Mechanics needing every common drive conversion

Technicians who already own a full range of individual adapters will find the set redundant. Buyers requiring impact-rated or locking adapters should look for those specific features elsewhere.

Drop each piece onto the corresponding drive

No tools are required for installation beyond the ratchet or breaker bar already in hand. The only common issue is mixing up the male and female ends when rushing, so verify the drive direction before applying torque.

Questions about this item

Which ratchet drives must I already have to use every adapter and U-joint in this 7-piece set?

You need ratchets or breaker bars with 1/4 in., 3/8 in. and 1/2 in. square drives to fit the three U-joints and four adapters supplied.

Will these chrome vanadium adapters and U-joints work with older sockets and ratchets I already own?

Yes — the set is designed to fit all brands of ratchets, bars and sockets, so legacy tools with standard square drives will connect without issue.

How can I confirm each piece meets the required ANSI standard after I unpack the set?

Every adapter and U-joint is manufactured to meet or exceed applicable ANSI standards, and the chrome vanadium steel construction provides the hardness and durability those standards specify.
