Description

GREAT FOR SECURITY APPLICATIONS: One-way lag screws cannot be removed with conventional tools—ideal for safes, security gates, and permanent fixtures.

DESIGNED FOR PERMANENT INSTALLATION: The one-way slotted head allows installation with a flat screwdriver but prevents removal with standard tools.

HEAT-TREATED GRADE 5 STEEL: Made from heat-treated Grade 5 steel to prevent breaking or snapping during installation into wood or structural materials.

PRE-DRILLING RECOMMENDED: Drill a pilot hole matching the screw diameter before driving to ensure proper alignment and prevent snapping during installation.

TRUSTED HILLMAN FASTENING SOLUTIONS: Hillman hardware products are engineered for consistent quality, dependable performance, and reliable fastening across construction, repair, and home improvement 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 $3 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 Hillman 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.
