14x1.5 Lug Bolt for Mercedes-Benz ML GLC S-Class - Solid One-Piece Fit

In this review the focus is on a set of 20 lug bolts designed for many Mercedes-Benz models; the bottom line is that these bolts are a practical, value-minded replacement for owners who need factory-style M14x1.5 hardware. They suit technicians or DIYers needing a complete set for multiple vehicles because the M14x1.5 thread and 17mm hex match common Mercedes wheel requirements, and the one-piece SCM435 construction addresses the common failure mode of two-piece bolts. Fit and finish are the most compelling reasons to consider this set.

Key Features

• One-piece design: Solid construction reduces the risk of expansion and cracking found in two-piece bolts, giving more reliable service under load.
• Wide vehicle fitment: Compatible with many Mercedes models from G-Class and ML-Class to recent S-Class and GLC variants, so a single kit covers multiple cars in a shop.
• Durable material: Made from SCM435 alloy steel with chrome coating, which improves hardness and resistance to wear compared with mild steel alternatives.
• Exact specification: M14x1.5 thread pitch, 69 mm overall length and 19 mm shank length deliver a correct fit where OEM part numbers 0009905407 and 9905407 are required.
• Installation convenience: CNC-machined threads and a 17mm hex allow use with a standard 17mm protective socket for clean, straightforward installation.

Who It's For

This set is best for Mercedes owners, independent mechanics, and fleet managers who need a full pack of OEM-style lug bolts to replace worn or damaged hardware across a range of models including ML, GLC, S-Class, E-Class, GL and G-Class variants. The one-piece design and full kit quantity make it practical for complete wheel jobs or for shops that service several Benz models.

Those who should look elsewhere include owners who require stainless steel or specialty coatings for heavy coastal exposure, and anyone who needs a custom length or an alternative seat type other than the specified ball seat. If extreme long-term rust resistance is the priority, a different finish or material might be preferable.

Pros & Cons

Pros

• Solid one-piece construction improves durability compared with two-piece designs.
• Accurate OEM-matching specs and broad fitment make it easy to replace factory bolts.
• Chrome coating and CNC threads give a clean appearance and ease of installation.

Cons

• Some users report corrosion over time in harsh environments, so long-term rust resistance may be limited.

Our Verdict

The 14x1.5 lug bolt set is a sensible, value-focused choice for Mercedes-Benz owners and shops that require factory-matching hardware across many models; its one-piece SCM435 construction and correct dimensions make installation reliable and repeatable, though those in severe salt-exposure climates should consider enhanced corrosion protection options.

Frequently Asked Questions

Will these bolts fit my Mercedes wheel?
They fit models that use M14x1.5 threads and a ball seat, including many ML, GLC, S-Class, E-Class, GL and G-Class years listed in the product fitment.

What socket do I need to install these?
Use a 17 mm protective lug nut socket or a 17 mm hex socket to avoid damaging the bolt head during installation.

Are these stainless steel?
No, they are made from SCM435 alloy steel with a chrome coating; they offer good hardness but may show corrosion sooner than stainless hardware in harsh conditions.
