SUCOSO 10-Piece Spline Lug Nut Socket Set 1/2in Drive — Black, Impact-Ready Slim-Wall

The SUCOSO 10-piece spline lug nut socket set is a compact, impact-ready toolkit with nine spline sockets and a 1/2" drive extension built for aftermarket spike and multi-spline lug nuts.

This set combines a range of spline profiles and sizes, a slim-walled design for tight wheel openings, and impact-rated construction so you can remove and install aftermarket lug nuts without changing tools. Finished with a corrosion-resistant black electrophoretic coating and supplied in a durable carrying case, it’s designed to live in a professional toolbox or a home garage.

Which lug nut types and sizes does this set work with?

The kit covers common spline and hex profiles used on aftermarket spike and specialty lug nuts. It includes both 5- through 12-spline options plus a 19 mm hex adapter so you can work with a wide variety of aftermarket wheels and bolts.

• Included sockets: 5-spline 3/4", 6-spline 41/64" and 45/64", 7-spline 3/4", 10-spline 23/32" and 13/16", 12-spline 11/16" and 13/16", plus 19 mm hex (SAE).
• 1/2" drive impact extension: 3" length for reach in recessed bolts.
• Compatible with many aftermarket spike lug nuts and multi-spline patterns—verify nut diameter before use.

How durable and impact-ready are these sockets?

Each socket is manufactured from chrome-vanadium (CR-V) alloy and undergoes cold forging and heat treatment for enhanced toughness. The black electrophoretic coating helps resist corrosion and surface wear during frequent use with impact tools.

• CR-V alloy steel construction for strength and longevity.
• Cold forging and heat treatment reduce cracking and deformation under load.
• Coated finish protects against rust and scuffing from shop use.

Will these sockets damage my wheels or fit in tight openings?

The sockets are designed with thin walls to fit in narrow wheel openings common on aftermarket rims, reducing the chance of contact with the wheel face. However, always check the nut and wheel clearances to ensure proper fit and avoid cosmetic damage.

• Thin-walled profile minimizes the risk of scratching wheel surfaces.
• Slim design fits recessed or narrow lug access holes on many aftermarket wheels.
• Recommended: confirm lug nut diameter and wheel hole size before use.

How is the set stored and transported?

The kit comes organized in a sturdy carry case sized for shop shelves or a vehicle trunk. The case keeps sockets and the extension secure and easy to find, helping prevent lost pieces during mobile jobs or roadside use.

• Durable storage case for secure organization and quick access.
• Compact layout fits into mechanic toolboxes or emergency kits.
• Case construction resists damage from regular workshop environments.
