Anotace

This specification covers the requirements and corresponding test methods for quenched and tempered alloy steel socket set screws (SSS) having sizes of M1.6 through M24, hardnesses of 45 to 53 HRC, and belonging to ISO 898/5 property class 45H. These set screws are intended for compression applications only and are not customarily subjected to embrittlement tests. The screws shall be fabricated to a fine grain practice in standard surface finishes, and optional protective coating as specified in the purchase order. Sampled specimens shall undergo heat and product analysis for measurements of the chemical content for carbon, phosphorus, and sulfur. Appropriate tests shall also be performed to analyze the conformance of the screws to mechanical and other property requirements such as torque and torsional strength, microhardness, decarburization, and surface discontinuities.
