Vlier SML10A Threaded Spring Plunger M10 X 1.5 Steel

Product Description

The VLIER SML10A is a threaded spring plunger designed for use in positioning, indexing, and light-duty locking applications across a range of industrial and mechanical assemblies. The plunger features an M10 x 1.5 thread with a body and thread length of 0.866 inches and a steel body construction. The spring-loaded nose projects 0.118 inches beyond the body face, delivering an initial end force of 2.02 pounds and a final end force of 7.87 pounds. With a maximum plunger diameter of 0.157 inches and no locking element, this is a straightforward, standard-length plunger suited for repeatable detent or feed-stop functions in machined housings and tooling fixtures.

The SML10A is typically installed in precision-machined threaded bores in jigs, fixtures, machine tool components, and fabricated assemblies where a spring-loaded nose is needed to index or hold a workpiece or moving component in position. The standard plunger length configuration makes it a common choice for general-purpose mechanical positioning tasks in both light manufacturing and maintenance applications. Installation is performed by machinists, tool and die technicians, or maintenance mechanics working with threaded steel or aluminum housings.

Key Features

• M10 x 1.5 thread for direct installation into standard metric threaded bores
• Steel body and steel nose material for durability in industrial environments
• 0.866 inch thread and body length for standard-depth housings
• 2.02 pound initial end force and 7.87 pound final end force for light-duty detent applications
• 0.118 inch plunger projection provides positive indexing engagement
• No locking element - installs and adjusts with standard tooling

Compatibility

Designed as a direct-fit replacement or new-install spring plunger for machined assemblies, jigs, fixtures, and tooling components with M10 x 1.5 threaded bores requiring a standard-length spring plunger.

Installation Notes

Installation is performed by threading the SML10A into a clean, properly tapped M10 x 1.5 bore using an appropriate hex key or spanner tool on the body. Ensure the bore is free of debris and the thread engagement depth matches the 0.866 inch body length before final seating. No locking element is incorporated, so thread-locking compound may be applied at the installer's discretion based on application vibration requirements. Always confirm bore alignment and plunger projection clearance before assembly.
