Gibraltar 855000-G Round Spring Locating Stop Aluminum

Product Description

The GIBRALTAR 855000-G is a round spring locating stop designed for precision positioning and workholding applications in machining, assembly, and fixture-building operations. The stop features a 0.375-inch stop head outside diameter and a 0.125-inch stroke length, delivering a mid-end force of 10 pounds. The body is constructed from aluminum, keeping weight low while providing adequate rigidity for repetitive locating cycles. This style of spring stop is commonly installed by machinists, toolmakers, and fixture builders who need a reliable, repeatable reference point in jigs and fixtures.

The GIBRALTAR 855000-G suits light-duty locating tasks in machining fixtures, assembly jigs, and automated tooling setups. Its compact footprint, with an 11/16-inch body length and 7/8-inch body width, allows installation in space-constrained fixture plates. The 21/32-inch distance between mounting hole centers and the 19/32-inch distance from mounting hole to edge simplify layout on standard fixture plates and tooling blocks. The flat button inside diameter of 13/32 inches accommodates typical spring button configurations used in these applications.

Key Features

• 0.375-inch stop head outside diameter for consistent part location
• 0.125-inch stroke length suitable for light-duty spring compression cycles
• 10-pound mid-end force provides positive but non-marring contact
• Aluminum body construction reduces overall assembly weight
• 3/16-inch base thickness and 7/8-inch base width fit standard fixture plate layouts
• 13/32-inch overall height keeps the stop low-profile in tight fixture applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for machining jigs, assembly fixtures, and tooling plates that accept round spring locating stops with a 0.375-inch stop head outside diameter and standard two-hole mounting pattern.

Installation Notes

Installation is typically performed by machinists or toolmakers during fixture assembly or maintenance. Secure all mounting fasteners before applying any workpiece load to the stop. Verify that the mounting hole pattern on the fixture plate matches the 21/32-inch center-to-center dimension before drilling. Inspect the spring mechanism for free travel and proper return force before putting the fixture into production.
