Wagner Tuning Nickeled Head Stud Set for Exx BMW 320i / 520i

The Wagner Tuning Nickeled Head Stud Set for Exx BMW 320i / 520i is a premium engine hardware upgrade designed to provide maximum strength and reliability for BMW M20-powered models. Manufactured in Germany from specially developed high-strength steel and finished with a durable nickel coating for superior corrosion protection, these Pro-Series 18.8 stud bolts deliver significantly improved clamping force over factory head bolts to help prevent head lift under increased power and stress. Precision-engineered with rolled threads for enhanced durability and long-term performance, this complete stud kit is ideal for high-performance street builds, turbo conversions, and motorsport applications requiring uncompromising engine stability.

High-Quality Materials and Production

Wagner Tuning manufactures its Pro-Series 18.8 stud bolt sets in Germany using a specially developed high-strength steel that achieves a tensile strength of over 1,850 N/mm² after tempering. Rather than using conventional cut threads, all threads are precision-rolled, increasing thread flank strength by approximately 30% for superior durability. Each Pro-Series product is finished with a corrosion-resistant nickel coating or, optionally, a burnished treatment, ensuring long-term protection and reliable performance even under the most demanding operating conditions.

Easy Installation and Durability

Wagner Tuning engineers its Pro-Series stud bolts with an integrated hex socket drive on the head side for precise and easy installation. A conical section on the engine block side ensures that, when tightened, the nuts seat correctly in the threaded bore rather than on the thread flanks, protecting the threads during frequent assembly and disassembly in racing applications. One of the key advantages of Wagner Tuning’s Pro-Series over other manufacturers is the inclusion of matching high-strength nuts and, where required, washers in each kit, all rated to the same 1,850 N/mm² tensile strength standard.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
