Kielder Impact Sockets - Full Range with Pin & O-Ring (52mm Long) – KWT-125-PO RANGE

The Kielder Impact Sockets with Pin & O-Ring (52mm Long) are professional-grade, mid-length impact sockets engineered for high-torque applications where absolute socket retention is mandatory. Featuring an integrated safety locking system—comprising a Sheffield, UK-manufactured grade 303 stainless steel pin and a durable rubber O-ring—this system securely locks the socket onto your impact wrench's square drive, making it the ultimate choice for working at height or in fast-paced motorsport service environments.

Forged from high-quality Chrome Molybdenum (Cr-Mo) steel with reinforced inner walls and a compact 52mm overall length, these sockets combine high-stress durability with exceptional manoeuvrability in tight spaces and recessed wheel wells.

Why Choose the Kielder Pin & O-Ring Impact Socket Range?

A pin-secured impact socket range is essential for:

• Preventing dangerous socket drops when working at height on scaffolding, structural builds, or elevated platforms
• High-vibration motorsport pit stops where accidental socket detachment cannot be tolerated
• Reaching confined spaces and recessed fasteners using a compact 52mm length profile
• High-torque impact driving without wall distortion or premature wear
• Seamless pairing with compact 18V cordless impact wrenches

Unlike standard friction-fit sockets, the positive locking pin-and-ring mechanism locks the socket rigidly to the anvil for maximum safety and efficiency.

Frequently Asked Questions

How does the pin and O-ring mechanism work?

The stainless steel pin passes through the cross-hole of the socket and the impact wrench anvil to lock them together, while the rubber O-ring stretches around the exterior groove to keep the pin firmly in place.

Where are the locking pins made?

The stainless steel retaining pins are precision-manufactured from grade 303 steel in Sheffield, UK.

What is the advantage of a 52mm length?

At 52mm, it bridges the gap between bulky deep sockets and shallow short sockets, providing optimal clearance in tight spaces without losing reach.

Are the sockets covered by a warranty?

Yes. They are backed by Kielder's lifetime guarantee against breakage and structural failure.
