Cheap Class 10.9 Steel Hex Bolt, Zinc Blue-Chromate Plated Finish, Metric, Metric (Coarse) Threads, Meets DIN 933/ISO 898 Specifications, M16-2 Thread Size, 40mm Length, Fully Threaded, Pack of 25
Hex bolts have a chamfered point to aid insertion into a tapped hole or nut. Length is measured from under the head.Class 10.9 fasteners are typically made of a medium-carbon alloy steel that is quenched and tempered, with 830 MPa proof load and 1040 MPa tensile strength. It has superior hardness for usage in applications where strength is a primary concern. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch). Zinc Plating helps to prevent corrosion.Hex head fasteners can be driven with simple wrenches, and require minimal clearance above the fastener because they can be driven or loosened from the side. A threaded fastener’s size name includes information about the major external diameter (in millimet
