If you want a compact, corrosion-resistant solution for specific M5 mounting points in thin-walled structures that demands a waterproof seal against the elements, choose JMFGR 10PCS; if you need a comprehensive, all-in-one hardware kit with a larger volume of fasteners and aluminum durability for extensive fairing repairs or high-speed stability, choose Parliky 20pcs.
The decision between these two options isn't about which brand is "better" in a vacuum; it is strictly about what your project requires right now. One offers specialized precision and material resilience for single-point fixes, while the other provides breadth and structural strength for broader maintenance tasks. You are likely standing at a crossroads trying to decide whether to buy a focused pack of well nuts or a full assortment of screws, clips, and grommets. I have analyzed the design specifications and intended use cases for both to help you cut through the noise and make the call without second-guessing yourself.
• JMFGR 10PCS: Strengths include a brass insert for superior corrosion resistance and a rubber sleeve designed specifically to create a tight, vibration-proof seal in irregular holes; the trade-off is the lower unit count (only 10) and the need to source separate screws for installation.
• Parliky 20pcs: Strengths lie in its complete nature as an assortment kit containing screws, grommets, and clips alongside well nuts, plus aluminum alloy construction for maximum security at high speeds; the trade-off is the absence of the brass insert feature and a different dimensional profile compared to the dedicated M5 well nuts.
• Who this is for: Choose JMFGR if you need to replace a few damaged fasteners on a windshield or fender where sealing out water is critical; choose Parliky if you are doing a full fairing restoration or need a bulk supply of various fastener types for a DIY repair job.
The JMFGR 10PCS Rubber Well Nuts are engineered for a very specific problem: creating a secure, sealed thread in materials that are too thin or irregular to hold a standard screw effectively. The core of their design philosophy is the combination of high-quality rubber and a brass insert. When you tighten the screw, the rubber sleeve expands radially, pressing firmly against the hole wall. This action does more than just hold the part in place; it creates a waterproof barrier that stops leakage and eliminates vibration damage. If you live in a humid region or frequently ride in wet conditions, this sealing capability is not a luxury; it is a necessity to prevent rust and component failure.
This product is ideal for riders who need to replace a small number of fasteners on motorcycles, kayaks, canoes, or boats. The brass insert is the standout feature here. Brass offers outstanding corrosion resistance, adapting to harsh environments without rusting even after long-term exposure. This makes it particularly suitable for marine applications or motorcycles that see a lot of road grime and moisture. The package includes 10 nuts in the M5 size, which measures approximately 0.47 by 0.47 by 0.55 inches. While ten might seem like a modest quantity, it is sufficient for daily replacement needs or fixing multiple spots on a single vehicle without overbuying.

However, you should skip this option if you are looking for a complete hardware overhaul or if you do not already have compatible screws on hand. The JMFGR pack contains only the well nuts themselves. You must drill a hole of the appropriate size, insert the nut, and then pass a separate screw through your bracket to thread into the nut. If you need a kit that includes the screws, grommets, and clips all in one box, this is not the right tool for the job. It is a specialized component for those who value the specific mechanical properties of brass and rubber expansion over the convenience of an all-in-one assortment.
The Parliky 20pcs kit takes a different approach, focusing on versatility and structural integrity for the entire motorcycle assembly. Instead of offering just the well nuts, this kit is a comprehensive fastener assortment that includes well nuts, windscreen bolts, grommets, and clip nuts. The primary material advantage here is the use of aluminum alloy. Aluminum provides robust construction and optimal resistance against weather, scratches, and wear over time. Unlike the brass insert found in the JMFGR version, the aluminum components in the Parliky kit are designed to resist harsh elements while maintaining a strong and reliable fix for your motorcycle windshield, ensuring the fairing stays in place even at high speeds.
This kit is perfect for enthusiasts who are tackling a major DIY repair or a full maintenance session. The inclusion of 20 pieces means you have enough fasteners to handle multiple mounting points across the bike. Whether you are securing body parts, bumpers, fenders, or the windshield itself, the variety within the kit covers the essential needs. The design prioritizes stable installation, preventing rattling during fast or off-road rides. The black finish adds a layer of aesthetic consistency, blending seamlessly with most motorcycle fairings and windshields. The dimensions of the items in the kit are roughly 0.43 by 0.79 by 0.43 inches, offering a slightly different footprint than the dedicated M5 well nuts.
You should consider the Parliky 20pcs if you want to avoid buying multiple separate packages to get everything you need. It caters to all essential motorcycle fastener assortment needs in a single purchase. However, if your priority is purely the anti-corrosion performance of a brass insert in a wet environment, you might find the aluminum construction less ideal for that specific niche. Furthermore, if you only need to replace one or two specific M5 well nuts and don't require the extra screws or grommets included in the box, this kit might contain more than you actually need for a quick fix.
• Best for waterproof sealing in thin walls → JMFGR 10PCS: The radial expansion of the rubber sleeve combined with the brass insert creates a superior seal against water and vibration compared to standard aluminum kits.
• Best for high-speed stability and rattling prevention → Parliky 20pcs: The aluminum alloy construction and comprehensive bolt kit are specifically marketed to keep fairings secure during fast or off-road riding.
• Best for corrosion resistance in harsh environments → JMFGR 10PCS: Brass is inherently more resistant to rust than aluminum, making it the better choice for boats, kayaks, or bikes exposed to salt and heavy rain.
• Best value for a full repair job → Parliky 20pcs: Getting screws, grommets, clips, and nuts in one box saves you from hunting down individual components for a complete fairing overhaul.
• Best for simple, targeted replacements → JMFGR 10PCS: If you only need to fix a few loose spots and don't want excess hardware cluttering your toolbox, the smaller, focused pack is more efficient.
• Best for versatile fitment → Parliky 20pcs: The assortment includes various fastener types, allowing you to address different mounting requirements on a single motorcycle or vehicle.
• Best for long-term durability in wet climates → JMFGR 10PCS: The brass insert ensures the threaded point will not corrode, extending the life of the fastening system in damp conditions.
• Best for ease of sourcing → Parliky 20pcs: Having the screws included means you can start the installation immediately without needing to match thread sizes separately.
In my opinion, the Parliky 20pcs is the smarter buy for most general motorcycle owners, especially those living in hot climates where heat cycles and sun exposure demand durable, scratch-resistant hardware. The aluminum alloy construction handles the thermal stress and UV exposure well, and having the complete set of screws and grommets means you won't be left stranded if another fastener fails later. However, if your primary concern is keeping water out of a thin-walled panel on a boat or kayak, the JMFGR 10PCS with its brass and rubber seal is the undeniable winner. For the average rider looking to secure a windshield or fairing with confidence, the comprehensive nature of the Parliky kit offers better peace of mind.
Yes, both products are designed to withstand harsh environments. The JMFGR uses brass for corrosion resistance, while the Parliky uses aluminum alloy for weather and scratch resistance, making both viable for extreme heat and humidity.
Yes, the JMFGR 10PCS pack contains only the well nuts. You must provide your own M5 screws to install them, whereas the Parliky kit includes the necessary screws and bolts in the box.
