Description

NYLON INSERT LOCK NUTS RESIST VIBRATION LOOSENING: 5/16 in.-18 nylon insert stop nuts grip bolt threads as the nut is tightened, preventing loosening from vibration, movement, or repeated use in mechanical and construction assemblies.

BUILT-IN NYLON INSERT FOR RELIABLE LOCKING PERFORMANCE: Integrated nylon locking insert creates friction against bolt threads during tightening, keeping the nut firmly in place and reducing back-off risk over time in demanding fastening uses.

COMPATIBLE WITH 5/16 IN.-18 COARSE THREAD BOLTS AND RODS: Engineered for 5/16 in.-18 coarse thread bolts and threaded rods, ensuring proper thread engagement and dependable fastening in construction hardware and mechanical assemblies.

ZINC-PLATED STEEL FOR CORROSION RESISTANCE: Durable steel with zinc-plated coating provides moderate rust protection for general-purpose fastening applications. Dependable performance in construction and mechanical installations. 100-piece pack.

TRUSTED HILLMAN FASTENING SOLUTIONS: Hillman hardware products are engineered for consistent quality, dependable performance, and reliable fastening across construction, repair, and home improvement project 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 $11 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.
