MACHINE SCREWS
ISO 7046-1 Cross Recessed Countersunk Machine Screws
Countersunk machine screws with cross recess h or z; specify one for specified metal and equipment assemblies.
Product Overview
A flat countersunk head seats within a machined recess, leaving a flush upper surface for panels and fittings. The cross recess must match the assembly bit to avoid cam-out and drive damage. This steel, class 4.8 product family is appropriate to describe separately from other countersunk screw material or strength specifications.
For an accurate quotation, specify the thread size, nominal length, material requirement and surface finish, together with the intended mating component. Dimensions, inspection requirements and the exact material and finish combination must be agreed before order confirmation.
