HPI Savage XL Screw Guide

Finding the Right Flanged Screw for Your HPI Savage XL 5.9 GTXL-6

The HPI Savage XL 5.9 GTXL-6 is a legendary piece of RC engineering, known for its sheer power, robust build, and its ability to tackle virtually any terrain. When it comes to maintaining such a potent machine, having the correct replacement parts is absolutely crucial. One common question that arises for owners is about the specific size of the flanged screws used in various parts of the truck, particularly for wheel attachment or other critical areas. Fortunately, with a bit of digging, we can pinpoint the exact specifications you need to keep your Savage XL performing at its peak.

The HPI Savage XL 5.9 GTXL-6 is a beast of an RC vehicle, an evolution of the already formidable Savage X chassis. Its 'XL' designation signifies its larger size and enhanced capabilities, featuring an XtraLong TVP chassis, an XtraLong wheelbase, and an XtraLarge 5.9cc engine. This truck is built for durability and performance, and as such, uses a variety of high-quality components. Understanding the specific hardware, like the flanged screws, is part of ensuring you can carry out effective maintenance and repairs.

Understanding Flanged Screws in RC Cars

Flanged screws, often referred to as 'shoulder screws' or 'collar screws', are distinguished by the integrated flange or collar beneath the head. This flange acts as a built-in washer, distributing pressure over a wider area and preventing the screw from digging into the material it's fastening. In RC cars, particularly in high-stress applications like attaching wheels or securing suspension components, these flanged screws are invaluable for their ability to provide a secure and reliable connection without damaging delicate parts. They also simplify assembly by combining two components (a screw and a washer) into one.

The Specific Screw for the HPI Savage XL 5.9 GTXL-6

Based on available information and common HPI part specifications, the specific flanged screw often sought for applications on the HPI Savage XL 5.9 GTXL-6, such as wheel mounting, is the:

TP. Flanged Screw M2.6x12mm (Hex Socket/6pcs)

Let's break down what this means:

• TP: This often denotes the type of threading or a specific manufacturer's designation.
• Flanged Screw: As discussed, this indicates the screw has an integrated flange.
• M2.6: This is the metric thread size. 'M' signifies metric, and '2.6' refers to the nominal diameter of the screw's thread in millimeters. This is a relatively small but strong screw size commonly used in RC applications for precision and weight saving.
• x12mm: This indicates the length of the screw's shank, from the underside of the head to the tip, is 12 millimeters.
• (Hex Socket/6pcs): This specifies that the screw head requires a hex wrench (also known as an Allen key) for tightening and loosening, and that these screws are typically sold in packs of six.

This particular screw size is frequently used for securing the wheel hubs or other components where a compact, yet secure, fastening is required. It's always a good idea to double-check your specific model's manual or the exploded diagrams provided by HPI if you are unsure, as different areas of the truck might utilise slightly different hardware.

Why the Right Size Matters

Using the correct size and type of screw is paramount for the longevity and performance of your HPI Savage XL 5.9 GTXL-6. Here's why:

• Structural Integrity: The wrong size screw can lead to stripped threads, loose connections, or even component failure. For instance, a screw that is too short won't provide adequate grip, while one that is too long might interfere with moving parts or strip the receiving threads.
• Material Damage: Using a screw without a flange where one is needed can cause the head to sink into softer materials like plastic or aluminium, potentially cracking or deforming them. The flange on the M2.6x12mm screw helps prevent this.
• Performance: A secure connection ensures that components like wheels are properly attached, allowing for optimal power transfer and handling. Loose parts can lead to wobbling, reduced efficiency, and unpredictable behaviour on the track or trail.
• Ease of Maintenance: Having the correct tools and parts, like the proper hex wrench for these M2.6 screws, makes maintenance tasks quicker and more efficient.

Where to Find Replacement Screws

Specialty RC hobby shops, both online and brick-and-mortar, are the best places to source genuine HPI parts or high-quality compatible hardware. Retailers like Wheelspin Models, which specifically mentions selling HPI Savage XL 5.9 GTXL-6 spares, are excellent resources. When purchasing, always ensure you are buying the correct specification (M2.6x12mm flanged hex socket screws) to avoid disappointment.

General Maintenance Tips for Your Savage XL

Beyond just screws, keeping your Savage XL in top condition involves regular checks and maintenance:

Pre-Run Checks:

• Inspect all screws and ensure they are tight.
• Check for any loose or damaged suspension components.
• Verify the fuel lines and connections are secure.
• Ensure the battery packs (transmitter and receiver) are charged.
• Check the tire condition and ensure they are securely mounted to the wheels.

Post-Run Maintenance:

• Clean the truck, especially the drivetrain and suspension, to remove dirt and debris.
• Inspect for any signs of damage or wear on parts like the driveshafts, differentials, and shocks.
• Check and clean the air filter.
• Lubricate moving parts as per the manual's recommendations.
• Inspect the clutch bell and spur gear for wear.

What's Included in the Savage XL Manual?

The Savage XL manual is an invaluable resource for any owner. It typically contains:

• Exploded Diagrams: These detailed illustrations show every part of the truck and how they fit together, crucial for identifying specific components and their part numbers.
• Parts List: A comprehensive list of all the parts used in the truck, often with their corresponding HPI part numbers.
• Assembly and Disassembly Instructions: Step-by-step guides for taking apart and putting back together various sections of the truck.
• Maintenance Procedures: Recommendations for lubrication, cleaning, and general upkeep.
• Troubleshooting Guide: Help for diagnosing and fixing common problems.
• Setup and Tuning: Advice on adjusting the suspension, engine, and other systems for optimal performance.

The manual emphasizes the 'Size Matters' philosophy of the Savage XL, detailing its larger dimensions and the robust components that make it so capable. It highlights features like the XtraLong TVP chassis, XtraLarge Terra Pin tires, Big Bore shocks, and heavy-duty drivetrain components, all of which contribute to its legendary durability.

Frequently Asked Questions (FAQ)

Q1: Can I use a regular M2.6 screw instead of a flanged one?
While technically possible in some non-critical applications, it is strongly discouraged for areas like wheel mounting. The flange provides crucial pressure distribution and prevents damage to the material. Always use the specified flanged screws for the intended purpose.

Q2: Where can I find the HPI Savage XL 5.9 GTXL-6 manual?
You can usually download the manual directly from the official HPI Racing website. Alternatively, many hobby shops that sell HPI parts will have links to PDF versions of the manuals.

Q3: Are there other screw sizes I should be aware of for the Savage XL?
Yes, the Savage XL uses a variety of metric screw sizes, including M3, M4, and others, depending on the specific component. It's always best to consult the parts list and exploded diagrams in your manual to identify the correct part numbers for any replacements needed.

Q4: What does 'Hex Socket' mean for a screw?
'Hex Socket' refers to the drive type on the screw head. It has a hexagonal recess that requires a hex wrench (Allen key) to tighten or loosen it. This provides a better grip and allows for more torque to be applied compared to Phillips or flathead screws.

Q5: How often should I check my screws?
It's good practice to perform a quick check of all accessible screws before each running session. A more thorough check and tightening should be done after a particularly rough run or as part of your regular maintenance routine.

Conclusion

Maintaining your HPI Savage XL 5.9 GTXL-6 is key to enjoying its immense power and unrivalled off-road capability. Knowing the specific hardware, such as the TP. Flanged Screw M2.6x12mm, is a vital piece of knowledge for any owner. By using the correct parts and performing regular maintenance, you ensure your Savage XL remains a reliable and thrilling machine for countless adventures.
