Overview

The Losi 8-32 x 1/8 inch Cup Point Set Screws represent an essential component for RC enthusiasts across the UK who demand precision engineering and reliable performance in their RC cars, buggies, trucks and crawlers. These high-quality grub screws are manufactured by Losi, a recognised leader in RC vehicle components and spare parts, and are designed to provide secure fastening in applications where standard screw heads would be impractical. Whether you're a seasoned competitor fine-tuning your race-ready RC buggy, a weekend basher maintaining your RC monster truck, or an RC hobbyist building your first custom machine, having the correct specification fasteners in your toolkit is fundamental to achieving consistent performance and longevity.

Cup point set screws serve a critical function in RC mechanics, gripping securely into dimpled or specially prepared surfaces to prevent slippage during operation. These particular Losi setscrews are manufactured to exacting tolerances and are sold as a pack of eight individual pieces, making them ideal for repairing multiple vehicles, maintaining backup inventory, or stocking your workshop with genuine OEM (Original Equipment Manufacturer) spares. The hex head driver type ensures you can apply torque efficiently using standard hex key tools, whilst the cup point design delivers superior holding power compared to flat point alternatives, making these setscrews an excellent choice for demanding RC applications.

RC Model Shop stocks genuine Losi replacement parts and components, and we understand that serious RC enthusiasts need reliable, authentic spares to keep their vehicles performing at their best. The Losi 8-32 x 1/8 inch Cup Point Set Screws are engineered to OEM specifications and represent the same quality standard you'll find throughout the Losi range of RC vehicles and components available across the UK.

Key Features

• Cup Point Design — The distinctive cup-shaped point on these setscrews bites into dimpled surfaces and provides superior gripping power compared to flat point alternatives, ensuring fasteners remain secure under vibration and operational stress in your RC car or truck.
• 8-32 Thread Specification — These setscrews feature an 8-32 Unified National Coarse (UNC) thread size, a standard specification across numerous Losi RC vehicles and components, ensuring compatibility with many models in the Losi range and reducing the need to stock multiple thread sizes.
• 1/8 Inch Length — The 1/8 inch length makes these setscrews ideal for applications requiring shallow penetration, such as securing pulleys, gears, and shafts where longer fasteners would prove impractical or cause interference with adjacent components.
• Hex Head Driver Type — The grub screw features a hexagonal socket head, allowing you to apply consistent torque using standard hex keys or L-shaped hex drivers, ensuring secure tightening without damaging the fastener or surrounding components during installation and adjustment.
• Pack of Eight Pieces — This convenient pack contains eight individual setscrews, providing sufficient quantity for vehicle repairs, building multiple machines, or maintaining a well-stocked spare parts inventory for your RC workshop and support equipment.
• Genuine Losi Manufacturing — These setscrews are authentic Losi replacement parts, manufactured to the same exacting standards and tolerances as the fasteners supplied in genuine Losi vehicle kits, guaranteeing compatibility and performance across Losi RC models and components.

Technical Performance

The Losi 8-32 x 1/8 inch Cup Point Set Screws represent precision engineering applied to fastening solutions for RC vehicles. The 8-32 thread specification refers to the number eight machine screw size with 32 threads per inch, a standard UNC (Unified National Coarse) specification widely adopted across the RC industry and particularly prevalent in Losi RC cars, buggies, trucks and related components. The 1/8 inch length (approximately 3.18mm) provides shallow penetration suitable for securing small precision components such as motor pinions, drive shafts, steering linkages, and adjustment points where deeper fasteners would prove unnecessary or potentially dangerous. The cup point design features a distinctive concave tip that creates a gripping surface when pressed into a corresponding dimple on the receiving component, distributing pressure across a wider area than traditional flat point setscrews and dramatically reducing the risk of slippage under the vibration and shock loads inherent in RC vehicle operation. The hex head driver type facilitates repeatable, consistent torque application, essential when working with precision RC components where over-tightening can strip threads or damage delicate parts, whilst under-tightening can result in component creep and performance degradation. These fasteners are manufactured from quality steel, hardened and finished to resist corrosion and wear even in demanding outdoor RC environments common throughout the UK. The combination of precise thread pitch, optimised point geometry, and robust material selection makes these setscrews an excellent choice for RC enthusiasts seeking genuine replacement fasteners that meet OEM specifications and deliver reliable performance across multiple RC vehicles and applications.

Frequently Asked Questions

• What are cup point set screws used for in RC vehicles? — Cup point set screws are used to secure small rotating or fixed components such as motor pinions, drive shafts, servo horns, and adjustment mechanisms to larger parts. The cup-shaped point bites into a dimple on the receiving component, preventing the screw from rotating or slipping under vibration and operational stress, which is critical in RC cars and trucks where movement of fasteners can degrade performance and potentially cause vehicle failure.
• What is the difference between cup point and flat point set screws? — Cup point set screws feature a concave, dimpled tip that grips into a corresponding dimple on the receiving component, distributing holding force across a wider area and providing superior gripping power. Flat point set screws have a completely flat end and grip only through surface contact, making them more prone to slipping under vibration. For demanding RC applications, cup point setscrews are generally the preferred choice.
• What thread size is 8-32 and why does it matter? — The 8-32 specification refers to an 8-size machine screw with 32 threads per inch (UNC standard). This is a common specification in Losi RC vehicles and components, ensuring compatibility with a wide range of models and replacement parts available within the Losi ecosystem. Using the correct thread size prevents damage to component threads and ensures secure, repeatable fastening.
• Are these genuine Losi parts? — Yes, these are genuine Losi replacement parts, manufactured to OEM specifications. They are sold under the Losi part number Z-LOSA6298 and carry an EAN code confirming their authenticity, ensuring you receive fasteners engineered to the same standards as components supplied in official Losi RC vehicle kits.
• What tools do I need to install these set screws? — You will need a hex key (Allen key) that fits the hexagonal socket head. The appropriate hex key size will depend on the specific socket diameter, typically ranging from 1.5mm to 3mm for small RC fasteners. A small torque wrench is recommended if you want to apply consistent, repeatable torque during installation, helping prevent over-tightening of precision RC components.
• How many set screws do I need for my RC vehicle? — This pack contains eight setscrews, which should cover most repair and maintenance scenarios for a single RC vehicle. If you're building multiple vehicles or maintaining a comprehensive spare parts inventory, you may wish to stock multiple packs to ensure you never run short of fasteners.
• Can I use these set screws on other RC brands besides Losi? — Potentially yes, provided the receiving component has the correct 8-32 thread holes and cup point dimples. However, genuine Losi setscrews are specifically engineered for Losi vehicles and components, so they are most reliably used with Losi RC cars, trucks, and related parts available through UK RC retailers.
