Stainless Steel Cage Nuts
Product Overview
Stainless steel cage nuts are an essential type of fastener used in a wide range of industrial and commercial applications. Also known as captive or square nuts, these components consist of a square nut trapped in a spring steel cage that wraps around it. The cage holds the nut in place and provides flexibility during installation, making them ideal for applications where traditional nuts are not suitable. Their stainless steel construction ensures excellent corrosion and rust resistance, making them suitable for environments exposed to moisture, chemicals, or extreme temperatures.
At Flybear Fastener, we offer stainless steel cage nuts designed to deliver superior performance and durability for any application where high-strength and corrosion resistance are paramount.

Material Introduction and Production Process
Our stainless steel cage nuts are crafted using premium-grade stainless steel alloys, primarily 304 and 316, known for their superior corrosion resistance and mechanical properties. The spring cage is manufactured from high-tensile spring steel, offering flexibility and ease of installation without compromising strength.
Production Process:
- Precision Material Cutting – raw materials are pre-cut based on desired sizes.
- Nut Forming – using CNC machining or stamping.
- Thread Tapping – ensuring accurate internal threading.
- Cage Formation – stamped and shaped to secure nuts.
- Assembly – Nut inserted and locked within the cage structure.
- Surface Treatment – optional electro-zinc plating for enhanced protection.
- Quality Inspection – conducted at multiple intervals for dimensional and functional accuracy.
Typical Applications Across Industries
Stainless steel cage nuts are commonly used in the following fields:
- Server racks and IT enclosures
- Automotive assemblies
- Aerospace and defense systems
- Industrial machinery
- Telecom cabinets
- Consumer electronics
- Marine equipment
They provide a versatile fastening solution for enabling front-access mounting in racks or enclosures without requiring rear-entry threading.
