40mm Shank M14x1.5 Lug Bolts 20pc Ball Seat - Extended Black

In this review of the extended lug bolts the bottom line is simple: these 20-piece M14-1.5 ball seat bolts are for drivers adding wheel spacers who need extra thread length and a clean black finish. The reviewer found the bolts deliver precisely what the product promises - a 40mm extended shank that accommodates common spacer thicknesses and a durable electrophoresis black coating that resists corrosion. They are not OEM replacements, so the single biggest reason to buy is when you have spacers and require safe, longer wheel bolts that match Audi and Volkswagen ball seat applications.

Key Features

• Extended Shank: The 40mm thread length provides the additional engagement needed when using wheel spacers without relying on original bolts.
• Fitment Coverage: Designed to fit a wide range of Audi and Volkswagen models, making selection easier for owners of A3 through A8, TT, Q5/Q7 and many VW models.
• Thread and Seat: M14-1.5 thread and ball radius (R13) seat match compatible wheel bolt seats to ensure proper seating and clamping force.
• Construction: Cold headed steel construction gives solid strength for lug applications, suitable for spacer use when installed correctly.
• Corrosion Resistance: Electrophoresis black finish increases resistance to rust and keeps the bolts looking uniform on the wheel face.
• Hex Drive: Standard 17mm hex allows use with common sockets and torque tools for straightforward installation.

Who It's For

These extended lug bolts are best for Audi and Volkswagen owners who run wheel spacers and need additional thread length. They suit aftermarket wheels and spacer setups where OEM bolts are too short and a ball seat is required - examples include drivers of A3, A4, A5, A6, A7, A8, S and Q models plus many VW Golf, Jetta and Tiguan variants.

Not everyone should choose these bolts: they are not OEM-length replacements and must not be used without spacers. If you do not run spacers or your vehicle uses a conical or flat seat rather than a ball radius seat, look for the correct OEM-style bolts instead.

Pros & Cons

Pros

• Well finished black coating that customers report looks great on wheels and resists corrosion.
• Generous 40mm extended shank solves spacer clearance issues when matched to spacer thickness.
• Strong cold-headed steel construction offers durable performance for lug applications.
• Comes as a complete 20-piece set, convenient for four-wheel installs plus spares.

Cons

• Not an OEM-length replacement; incorrect use without spacers risks improper fit and safety issues.
• Fitment requires verifying your vehicle uses an R13 ball seat and M14-1.5 thread, which varies by year and model.

Frequently Asked Questions

Can I use these without wheel spacers?
No. These are extension lug bolts and are not intended as OEM-length replacements; they should not be used without spacers.

Will these fit my Audi or VW?
They fit models that use M14-1.5 thread and a ball radius (R13) seat including many Audi A and S models and many Volkswagen models, but verify seat type and thread for your specific year.

How should I install them?
Measure OEM bolt length and spacer thickness first, and during installation make sure each bolt turns 5-8 full turns before final torque to ensure proper engagement.
