Description
Product Overview
Prime-Line MP17051 one‑way barrel nuts are precision‑engineered fasteners designed for applications where security and durability are paramount. Constructed from high‑grade alloy steel and finished with a chrome‑plated coating, these nuts resist corrosion, wear, and tampering. The internal thread is a standard #10‑24 Unified National thread, fully threaded along the 5/8‑inch barrel length, providing a reliable mating surface for one‑way screws used in restroom partition systems, locker doors, and other privacy‑critical hardware.
The nuts feature a flat head style that sits flush against the mounting surface, reducing snag points and ensuring a clean, professional appearance. Each package contains 25 individually wrapped nuts, allowing for easy inventory management and quick access during installation or repair work. The compact dimensions—3.5 × 4 × 0.38 inches—make them suitable for tight spaces while the 0.16‑pound weight keeps handling effortless.

Usage
These one‑way barrel nuts excel in environments where tamper‑proof fastening is required. Typical installations include commercial restroom partitions, where the nuts secure the partition panels to the floor or wall without the risk of unauthorized removal. They are also ideal for locker room doors, privacy screens, and any application that uses a one‑way screw to prevent disassembly by end users.
Because the nuts are chrome‑plated, they maintain a bright, reflective finish that resists moisture and chemical exposure common in restroom settings. The alloy steel core provides the strength needed to withstand repeated opening and closing cycles, ensuring long‑term performance. Installers appreciate the consistent thread pitch and smooth engagement, which reduces installation time and minimizes the chance of cross‑threading.
When used with compatible one‑way screws, the barrel nut creates a secure, one‑directional lock that can only be removed with a special tool, adding an extra layer of security for facilities that require controlled access.

FAQ
What is a one‑way barrel nut?
A one‑way barrel nut is a cylindrical fastener with an internal thread that mates with a specially designed one‑way screw. The screw can be driven in to lock the assembly, but it cannot be removed without a special tool, providing tamper‑proof security.
Can these nuts be used with standard screws?
No. They are intended for use with one‑way screws that have a matching #10‑24 thread profile. Using standard screws may result in improper fit and reduced security.
Is the chrome finish durable in a restroom environment?
Yes. The chrome plating is applied to meet industry corrosion‑resistance standards, making it suitable for high‑humidity and cleaning‑chemical exposure typical of restroom settings.
How many nuts are included in each package?
Each package contains 25 individually wrapped barrel nuts, providing enough units for multiple installations or replacement needs.
