Gibraltar SSW10-5-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SSW10-5-G is a threaded spring plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 5/16-18 unified coarse thread with a 1 inch thread length and a stainless steel body for corrosion resistance. The plunger nose is steel and projects 3/16 inch (0.1875 inch) beyond the body face. Initial end force is 3 pounds and final end force is 15 pounds, making it suitable for applications that require a defined engagement feel without a locking element. Machinists, toolmakers, and maintenance technicians typically install these in jigs, fixtures, and machine components.

This spring plunger is used in industrial and trade maintenance settings where repeatable positioning or light retaining force is needed. Common applications include fixture alignment, panel indexing, drawer retention, and equipment assembly work. The stainless steel body makes it a reliable choice in environments with moderate moisture exposure or where mild corrosion resistance is required. It installs into any tapped 5/16-18 hole and does not require a locking element for standard installations.

Key Features

• 5/16-18 thread size fits standard tapped holes — no special tooling required
• Stainless steel body provides corrosion resistance in moderate-exposure environments
• 3 pounds initial end force and 15 pounds final end force for defined detent engagement
• 3/16 inch plunger projection (0.1875 inch) for consistent indexing depth
• No locking element — installs and adjusts with standard hex wrench (0.0937 inch hex size)
• Standard plunger length type for general-purpose mechanical assembly use

Compatibility

Designed as a standard-thread spring plunger for any application requiring a 5/16-18 tapped hole with a 1 inch thread engagement depth in jigs, fixtures, or mechanical assemblies.

Installation Notes

Installation requires a properly tapped 5/16-18 through or blind hole with sufficient depth to accept the 1 inch thread length. Use a hex wrench sized to the 0.0937 inch hex drive to thread the plunger in to the desired engagement depth. Power down or de-energize any equipment before installing or adjusting spring plungers in active assemblies. Do not overtighten — set depth to achieve the desired plunger projection and engagement force per the application requirements.
