Specifications:
The document outlines the specifications for threaded inserts designed for heat or ultrasonic embedding, specifically the S-Lok® and S-Lok®-K models. These inserts are made primarily from brass, with other materials available upon request. The tolerances adhere to ISO 2768-m standards, and the internal thread follows ISO 6H specifications.

Application:
These threaded inserts are used to create wear and vibration-resistant screw fasteners with high load capacity in plastics, particularly thermoset plastics. The inserts are embedded into pre-formed receiving holes, which are softened using heat or ultrasound.

Product Variants:
The document provides detailed specifications for various models of the S-Lok® and S-Lok®-K inserts, including internal and external diameters, head diameter, head height, and length. The dimensions are provided in millimeters.

Example:
An example is given for finding a threaded insert S-Lok® to Works Standard 860 without a head and with an internal thread M4, with the article number S-Lok® 860 000 040.800.

Dimensions and Guidelines:
The document includes tables listing the dimensions for different article numbers, specifying internal thread, external diameter, length, hole diameter, and minimum wall thickness. These dimensions serve as guidelines for selecting the appropriate insert for specific applications.
