Specs

• Dimensions: 1/4" hex, 4" length
• Finish: Plain
• Material: Aluminum
• Thread type: #4-40

Features

• Use case: Panel spacing and alignment in industrial enclosures, control panels, and machinery assemblies; suitable for applications requiring precise standoff distance between components.
• Mechanical compatibility: Female-Female thread ends accept #4-40 screws on both sides, enabling bilateral mounting and modular assembly; hex body supports torque transfer during assembly.
• Material properties: Plain aluminum provides low density, high strength-to-weight ratio, and compatibility with standard machining and anodizing processes; natural oxide layer offers basic corrosion resistance suitable for indoor environments.
• Finish and post-processing: No plating or coating; can be subjected to anodizing or painting if additional protection or color-coding is required, without affecting base dimensions.
• Packaging: 250 pieces per package, enabling bulk replacements and stocking for high-volume assembly lines.
• Ideal for: Electronics and automation OEMs, panel builders, machinery integrators, and maintenance teams performing modular equipment assembly in factory settings.
