Caphead screws are a critical part of RC assembly, offering superior clamping force and a clean, professional appearance compared to standard fasteners.
This pack contains eight individual 5-40 x 1/2 inch caphead screws, manufactured by Losi to the exacting standards you'd expect from one of the industry's most respected RC brands. Available from RC Model Shop, these genuine Losi screws are ideal for RC car enthusiasts in the UK who demand quality components that will keep their vehicles running reliably through countless hours of racing, bashing and off-road adventure. From competitive racers to weekend enthusiasts enjoying RC off-road buggies and trucks, having a supply of quality replacement screws is essential maintenance for any serious RC hobbyist.
Caphead screws, also known as socket head cap screws or Allen head screws, feature a hexagonal recess that requires an Allen key or hex driver for installation. This design provides several advantages over traditional Phillips or slotted screws: the hex socket distributes pressure more evenly across the fastener head, reducing the risk of stripping or damage during assembly and disassembly. For RC car builders and technicians, this reliability translates to faster, more confident maintenance work and fewer frustrating broken fasteners during critical moments.
Key Features
- 5-40 Thread Size — The 5-40 designation refers to a number 5 gauge with 40 threads per inch, making this a fine-pitch fastener suitable for precision RC applications where secure, rattle-free assembly is paramount. This size is widely used throughout Losi RC vehicle platforms and is a reliable choice for building, maintaining and upgrading your RC collection across the UK.
- 1/2 Inch Length — The half-inch length provides adequate engagement depth for common RC assembly scenarios, ensuring sufficient thread bite without protruding excessively through components. This length is ideal for panel fastening, electronics mounting, and suspension linkage assembly on Losi RC vehicles.
- Caphead Design — The distinctive hexagonal socket head offers a professional appearance whilst delivering superior mechanical advantage compared to Phillips or slotted alternatives. The caphead design ensures you can apply consistent torque without worrying about bit slippage or fastener damage during maintenance or rebuilding.
- Eight-Piece Pack — This generous eight-screw quantity ensures you have spares on hand for repairs, replacements, and upgrades. Whether you're fixing a broken fastener or assembling multiple RC vehicles, having this complete pack in your toolbox means you'll never be stranded without the right component.
- Genuine Losi Manufacturing — These are authentic Losi-branded fasteners, meeting the original equipment specifications used throughout Losi's RC vehicle lineup. Choosing genuine manufacturer parts guarantees compatibility and reliability that aftermarket alternatives simply cannot match.
Technical Performance
The Losi 5-40 x 1/2 inch Caphead Screw exemplifies precision engineering applied to one of the smallest but most critical components in any RC assembly. The 5-40 thread pitch is a fine-gauge specification that provides superior thread density and clamping force reliability, making these screws ideal for securing precision components on modern RC cars, buggies, trucks and crawlers. The caphead socket design accommodates standard hexagonal Allen keys, allowing technicians to apply controlled torque during installation without the risk of cam-out that plagues Phillips-head fasteners in high-vibration environments like RC vehicles. The 1/2 inch length (approximately 12.7mm) strikes an optimal balance for RC applications, providing sufficient thread engagement for reliable clamping without creating protrusions that could interfere with adjacent components or create snag points during off-road running. Built to OEM Losi standards using hardened steel construction, these fasteners resist stripping and maintain their integrity through countless assembly cycles. For RC enthusiasts who demand reliability during competition, casual weekend bashing, or meticulous restoration projects, genuine Losi fasteners like these represent a commitment to quality that directly impacts vehicle performance and longevity.

Frequently Asked Questions
- What size Allen key do I need for these Losi caphead screws? — The 5-40 caphead screw accommodates a standard hexagonal Allen key; typically this size uses a 3/32 inch or 2.4mm hex driver. Always ensure your Allen key fits snugly in the socket to avoid stripping the recess during installation or removal.
- Are these caphead screws suitable for all Losi RC vehicles? — The 5-40 x 1/2 inch size is commonly used across many Losi RC platforms including buggies, trucks, and crawlers. Consult your specific Losi vehicle manual to confirm compatibility before ordering, as different models may require alternative fastener sizes.
- Can I use these screws for RC vehicle repairs and maintenance? — Yes, absolutely. These caphead screws are ideal for replacing worn, stripped, or damaged fasteners on your Losi RC vehicle. Having a spare pack in your maintenance box ensures you can perform repairs quickly without waiting for additional parts to arrive.
- What is the difference between caphead screws and Phillips-head screws for RC applications? — Caphead (socket head) screws offer superior performance in RC vehicles compared to Phillips-head alternatives. The hexagonal socket distributes force more evenly, reducing the risk of stripping. The caphead design also accommodates higher torque application, provides a cleaner professional appearance, and resists loosening in high-vibration environments like RC cars undergoing intense off-road use.
- Why should I choose genuine Losi fasteners over cheaper alternatives? — Genuine Losi fasteners are engineered to precise OEM specifications, ensuring perfect compatibility with your Losi RC vehicle and consistent performance across assembly and maintenance cycles. Cheaper alternatives may feature inferior metallurgy, inconsistent threading, or dimensional variations that lead to stripping, poor clamping force, and frustrating failures during critical moments. For serious RC hobbyists, the modest investment in genuine components delivers substantial reliability dividends.
