The Light Source 7/32 x 2 Coil Pin is a heavy-duty, spring-tensioned fastener designed for rapid, secure, and reusable pinning in a wide array of staging, rigging, and construction applications. This specific pin, measuring 7/32 of an inch in diameter and 2 inches in length, is constructed from hardened steel and features an HBG-Zinc finish, which provides a robust barrier against corrosion, making it suitable for both indoor and outdoor use. Coil pins, also known as roll pins or spring pins, are hollow, slotted cylinders with a slight chamfer on each end. Their unique design allows them to be compressed during insertion into a drilled hole; once in place, the pin exerts constant outward radial pressure against the walls of the hole, creating a firm, vibration-resistant fit that locks components together without the need for threads, nuts, or secondary retainers.

The "heavy-duty" designation indicates a construction that can withstand significant shear forces, which are forces acting parallel to the cross-section of the pin. This makes it ideal for securing hinged connections, attaching levers and handles, aligning components in machinery, and as a safety or pivot pin in rigging hardware like shackles or turnbuckles. The HBG-Zinc (Heavy Bright Galvanized) finish offers a bright, silvery appearance and excellent protection against rust and corrosion, ensuring long-term reliability even in humid or demanding environments. The 2-inch length provides ample engagement for securing thick materials or multiple stacked components, while the 7/32-inch diameter offers a balance of strength and compatibility with standard drilled hole sizes.

This coil pin is an indispensable consumable in the toolkit of stagehands, riggers, mechanics, and fabricators. In entertainment, it is commonly used to secure adjustable mounting brackets, attach safety cables to hardware, and pin together modular truss and pipe components for quick assembly and strike. Its reusability is a key advantage; it can be driven out with a punch and reused many times, unlike cotter pins which are typically deformed during installation. The ease of installation and removal with a hammer and punch, combined with its reliable, vibration-proof hold, makes it a preferred choice for temporary but critical connections in touring equipment, temporary structures, and industrial maintenance. It embodies a simple yet highly effective mechanical solution for creating secure, semi-permanent pinned joints.
