Kielder 52mm Long Impact Socket Range (with Pin & O-Ring) – KWT-125-PO3

The Kielder 52mm Long Impact Socket Range is engineered for professional mechanics, motorsport service crews, and high-load industrial environments where mid-length clearance and absolute security are critical. Manufactured from high-grade Chrome Molybdenum (Cr-Mo) steel, these mid-size 52mm sockets combine a robust, reinforced inner wall with a slimline outer diameter, allowing effortless access into recessed wheel nut wells and tight spaces.

Designed specifically for use with high-torque impact wrenches, each socket features an integrated retaining pin and rubber O-ring safety system—making this range an essential choice for working at height or in fast-paced motorsport paddocks where socket retention is paramount.

Why Choose the Kielder 52mm Impact Socket Range?

A professional mid-length impact socket is essential for:

• Reaching recessed wheel nuts and tight mechanical spaces where standard deep sockets are too long and short sockets lack reach
• Secure, locked-on fastening during high-vibration applications or when working at height
• High-torque impact resistance without wall distortion or premature wear
• Even weight distribution along the socket length to optimize impact energy transfer
• Universal compatibility with Kielder 1/2" impact wrenches as well as all other major power tool brands

Unlike standard hand sockets, Cr-Mo impact construction flexes minutely under peak hammer blows to absorb stress, protecting both the fastener and the tool drive.

Key Benefits

• Mid-size 52mm overall length offers the ideal compromise between deep reach and compact clearance
• Includes safety pin and rubber O-ring locking mechanism to firmly secure the socket to the anvil
• Forged from high-grade Chrome Molybdenum steel for maximum tensile strength and durability
• Slimline outer profile with a reinforced inner wall for restricted wheel nut recesses
• Even weight distribution ensures balanced delivery of rotational impact force
• Backed by Kielder’s lifetime guarantee* against breakage

Who Is This For?

• Motorsport Service Crews: Essential for rapid, secure wheel changes during frantic race pit stops and stage rallies.
• Scaffolding & Height Technicians: Pin-and-ring locking ensures sockets cannot accidentally detach and fall when working at elevation.
• Automotive Workshop Mechanics: Perfect for dealing with sunken alloy wheel nuts and tight suspension components.
• Mobile Engineers: Rugged, impact-rated performance built to withstand daily trade abuse in service vans.

Frequently Asked Questions

What is the purpose of the pin and O-ring?

The steel pin locks the socket securely onto the impact wrench’s square drive, while the rubber O-ring stretches over the exterior to keep the pin locked firmly in place, preventing accidental detachment.

Are these sockets suitable for high-torque cordless impact wrenches?

Yes. They are forged from impact-grade Chrome Molybdenum steel explicitly designed to handle the intense peak torque delivered by 18V brushless impact wrenches.

Will these fit non-Kielder impact wrenches?

Yes. While optimized for Kielder 1/2" drive tools, they feature a universal square drive fitment compatible with all standard pneumatic and cordless impact brands.

What warranty is provided?

They are covered by Kielder's lifetime guarantee against manufacturing defects and structural breakage.
