About This Item
ASTM F1137/F1137M is the ASTM standard that covers phosphate/oil corrosion protective coatings for fasteners, providing a clear technical basis for evaluating this type of finish. It is used to define a common specification for coatings intended to help protect fastener surfaces from corrosion while supporting consistent product quality. For buyers, engineers, and quality teams, this standard matters because it helps align expectations for performance, material treatment, and compliance.
ASTM F1137/F1137M standard overview
The ASTM F1137/F1137M standard overview centers on a specification for phosphate/oil corrosion protective coatings applied to fasteners. As a product standard, it helps establish the technical requirements associated with this coating system rather than describing a general-purpose coating category. ASTM F1137/F1137M is therefore useful when purchasing, testing, or verifying fasteners that rely on phosphate/oil protection, especially where consistent surface treatment and corrosion resistance are important to the end use.
Where is ASTM F1137/F1137M used?
This standard is commonly used in fastener procurement, manufacturing, and quality control workflows where phosphate/oil-coated fasteners are specified. It is relevant when selecting or reviewing fasteners for assemblies that may face moisture, handling, or storage exposure and need a protective coating finish. ASTM F1137/F1137M may also be referenced during supplier qualification, incoming inspection, and product documentation to confirm that the coating system matches the intended specification.
Practical importance of ASTM F1137/F1137M
ASTM F1137/F1137M helps support consistent expectations for coated fasteners, which can reduce ambiguity during purchasing and inspection. By pointing to a recognized ASTM specification, it can improve communication between suppliers and customers and support more reliable product evaluation. In practice, the standard is valuable for compliance checks, specification control, and quality assurance where a phosphate/oil corrosion protective coating is part of the required fastener performance.
