Description
HARD-TO-FIND LONG SIZES: Eliminate the frustration of short screws. While most kits stop at 30mm, LUKAISEN offers a curated selection of M4 bolts ranging from 12mm up to an extra-long 60mm. It is the ultimate solution for thick furniture panels, door handle replacements, and deep-reach mechanical fastening.
MARINE-GRADE 304 STAINLESS STEEL: Forged from high-quality 304 stainless steel, these M4 fasteners provide superior strength and excellent corrosion resistance. Designed to perform in both indoor and outdoor environments, ensuring your repairs stay secure without the worry of unsightly surface rust.
CLASSIC PAN HEAD & PHILLIPS DRIVE: The flat-bottomed pan head design provides a large bearing surface for a firm grip, while the standard Phillips drive prevents cam-out and stripping. This combination ensures a professional, flush-fitting finish on appliances, brackets, and household hardware.
PRECISION METRIC THREADING: Manufactured to strict ISO metric standards, our M4 machine screws feature clean, sharp threads and consistent pitch. This ensures smooth installation into pre-tapped holes or with matching M4 nuts, making them ideal for high-precision DIY projects and electronics.
COMPACT & LABELED STORAGE: Organized in a durable, transparent organizer box with clear size dividers. The labeled compartments allow you to quickly identify and access the exact length you need (12mm to 60mm), keeping your workbench tidy and your projects moving forward.
The Missing Link in Your Hardware Collection
We've all been there: you're halfway through a repair only to find that the standard screws in your kit are just a few millimeters too short. The LUKAISEN 140PCS M4 Extra Long Assortment was specifically created to solve this problem. By extending the size range up to 60mm, we provide the versatility that standard hardware store sets simply don't offer.
Engineered for Tougher Tasks:
Whether you are mounting a new TV bracket, fixing a heavy-duty cabinet handle, or working on custom automotive detailing, M4 screws are the versatile workhorse you need. Crafted from 304 Stainless Steel, these bolts are built to handle the torque and resist the elements, making them a reliable choice for kitchen, bathroom, and outdoor applications.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $1 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for LuKaiSen products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
