Value Collection 1N.386 Tamper Resistant Spherical Nut 3/8-16

Product Description

The VALUE COLLECTION 1N.386 is a tamper resistant spherical fixture nut designed for applications requiring security fastening and resistance to unauthorized removal. Manufactured from alloy steel with a zinc plated finish, this nut features a 3/8-16 UNC right hand thread and stands 0.25 inches tall. The spherical dome profile prevents engagement by standard wrench or socket tools, making it appropriate for public installations, enclosures, and fixtures where vandal resistance is required. Installation typically requires a specialized driver bit matched to this nut style.

This fixture nut is suited for commercial and industrial fastening applications where tamper resistance is a priority. Common uses include securing electrical enclosures, fixture mounting hardware, public seating, signage, and access panels. The zinc plating provides moderate corrosion resistance for indoor and light outdoor environments. The 3/8-16 UNC thread standard ensures compatibility with standard inch-series threaded studs and bolts commonly found in structural and fixture assemblies.

Key Features

• Tamper resistant spherical profile resists removal with standard hand tools
• 3/8-16 UNC right hand thread for use with standard inch-series fastener systems
• Alloy steel construction provides high tensile strength
• Zinc plated finish for corrosion resistance in indoor and light outdoor use
• Compact 0.25 inch height suits low-clearance fixture installations

Compatibility

Designed for use with 3/8-16 UNC threaded studs, bolts, and threaded rod in standard inch-series fixture and structural assemblies requiring tamper resistant fastening.

Installation Notes

Installation and removal require a specialized tamper resistant driver tool matched to the spherical nut pattern — standard sockets and open-end wrenches will not engage this nut. Ensure the mating thread is clean and free of debris before assembly. Follow applicable fastener torque guidelines for alloy steel hardware at this thread size. Always de-energize or lock out equipment before servicing fasteners on live electrical or mechanical enclosures.
