These sockets are shorter than our standard length impact sockets on u-joints allowing access into tighter areas. One less connection point creates a stiffer joint reducing the loss of impact power.

Exact dimensions can be found in the specs section of each product.

30-Degree Working Angle

The joint rotates smoothly and continuously at up to a 30-degree angle.

6-Sided Pinless Joint

Our solid ball-and-socket-style joint is stronger than joints that use pins. The 6-sided ball operates more smoothly than 4-lug designs.

Parts and Assembly

The socket base and ball/socket are coated with a corrosion-resistant manganese phosphate finish.

The universal joint impact socket comes pre-lubricated with SuperLube Multi-Purpose Synthetic Grease (NLGI 2) with Syncolon® (PTFE). Maintain the lubrication using this grease or a comparable grease as needed to reduce wear over time.

6-Point Socket Opening

Provides an exact fit and maximum contact for hex fasteners.

Prevents Fastener Round-Off

Radiused corners prevent fastener round-off by applying force to a fastener’s flat sides, rather than its corners.

Two Size Markings

The size is marked in two ways on every socket—both as a high-visibility laser marking and a permanent stamped marking.

Drive Tool Retention

The universal joint works with both types of anvils found on 3/8 inch drive impact wrenches.
