Title FLASH #900 Stainless Steel Wheel Bead Locks – M5 Thread (Set of 12)

The FLASH #900 Wheel Bead Locks are a premium, ultra-reliable hardware upgrade engineered to eliminate tire slippage and critical air pressure loss under heavy cornering loads. Precision-machined from high-grade 316 marine-grade stainless steel, this comprehensive set of 12 bead screws offers unmatched resistance against paddock corrosion, cross-threading, and material fatigue—making them a vital investment for professional go-kart teams and serious owner-drivers alike.

Unlike standard, shallow bead screws that frequently strip or round out when changing tires in a hurry, the FLASH #900 locks feature an extra-deep 3.4mm hex pocket. This deep socket geometry drastically increases the surface area for your tools, providing positive engagement that prevents tool cam-out and slippage even under repeated usage. Additionally, each screw is sculpted with a smart, low-profile head that houses a specialized underside containment cavity. As you torque the screw down, this internal recess perfectly holds and shields the included premium rubber O-ring, ensuring an airtight pneumatic seal against your magnesium or aluminum rims without crushing or shearing the rubber.

Key Features:

• 316 Stainless Steel Construction: Forged from high-grade 316 stainless steel to ensure maximum thread durability and total resistance against rust, brake dust, and tire mounting fluids.

• Extra-Deep 3.4mm Hex Pocket: Significantly deeper than conventional hex bead retainers, minimizing the risk of stripping or rounding out during high-pressure race day tire changes.

• Underside O-Ring Cavity: A custom internal pocket under the low-profile screw head encapsulates the rubber seal as it compresses, preventing leaks without damaging the O-ring.

• Universal Metric M5 Thread: Standardized M5 threading ensures direct compatibility with nearly all professional metric karting rims on the market.

• Complete 12-Piece Track Pack: Supplied as a comprehensive set containing 12 premium bead screws and 12 matching protective O-rings—enough to fully outfit a standard set of kart racing wheels.

Frequently Asked Questions (FAQs):

• Which tools are recommended to install these bead locks without damaging them?

  While these locks are compatible with high-quality 3mm Allen keys, they are specifically optimized to pair with the FLASH #518 Bead Retainer Twirler or the FLASH #902 Palm Twirler Tool. Using these dedicated hand tools allows you to take full advantage of the deep 3.4mm hex cavity, giving you maximum spinning speed and precise torque feedback.

• Will these fit my standard OTK, AMV, or Edwards kart wheels?

  Yes, absolutely. The M5 thread specification is the absolute standard across modern go-kart racing wheels. Whether you are running magnesium OTK rims, aluminum AMV wheels, or Douglas (DWT) rims, these M5 screws will thread directly into place.

• Can I purchase replacement rubber seals later if these get lost or worn?

  Yes. The rubber seals will eventually show wear after multiple tire changes. We carry the genuine FLASH #903 replacement O-rings as a standalone service item so you can refresh your airtight seals without needing to buy a whole new set of stainless steel screws.
