Gibraltar 10004P Threaded Ball Plunger 8-36 Stainless Steel

Product Description

The GIBRALTAR 10004P is a threaded ball plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. It features an 8-36 thread size, a 0.093-inch stainless steel ball diameter, and an 11/32-inch body length. Initial end force is 0.5 pounds, with a final end force of 1.25 pounds and a maximum ball reach of 0.025 inches. Both the body and ball are constructed from stainless steel, offering corrosion resistance in demanding environments. Machinists, tool and die makers, and maintenance technicians install these plungers in jigs, fixtures, and precision mechanical components.

Threaded ball plungers like the 10004P are used in light-duty detent and positioning applications across manufacturing, maintenance, and industrial assembly settings. The 8-36 thread size suits fine-threaded installations in small machined housings or assemblies. The stainless steel construction makes this plunger appropriate for environments where moisture, cleaning agents, or mild corrosives are present. It is sold individually and suited for single-point replacement or prototype builds where low-quantity procurement is required.

Key Features

• 8-36 thread size for fine-thread installations in small machined components
• 0.093-inch stainless steel ball diameter with 0.025-inch maximum ball reach
• 0.5-pound initial end force and 1.25-pound final end force for light detent applications
• Stainless steel body and ball for corrosion resistance
• No locking element — standard spring-loaded design
• Purple color code for quick field identification

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies requiring an 8-36 threaded ball plunger with a 0.093-inch ball diameter and 11/32-inch body length.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a hex wrench or driver matched to the plunger body. Ensure the receiving threaded bore is clean and free of debris before installation. Do not overtighten — the plunger body is stainless steel and fine-threaded, making it susceptible to thread galling if torque is excessive. Verify ball travel is unobstructed after seating.
