The images include several pointed, coarse-threaded and sharp-end screw forms that visually correspond to self-tapping or self-drilling-style product directions. The exact classification should be confirmed from the point geometry, thread profile and intended mating material.

Custom CNC screws are drawing-based screws produced or finished to a specified head, drive, thread, length, point, material and surface requirement. They are suitable when a standard screw does not match the assembly.
Precision machine screws are generally used in assemblies with a defined mating thread, such as machinery, fixtures, equipment, instruments and OEM products. Final suitability depends on the drawing and assembly conditions.
Yes. Custom self tapping screws can be reviewed by point shape, thread profile, head, drive, length, material and finish. The customer should identify the material being fastened, such as sheet metal, wood or plastic.
The head and drive can be specified as part of the drawing or sample review. Visible image examples include socket-style, slotted, Phillips, countersunk and rounded or pan-style heads.
Black, silver, gold, purple, blue and green appearances are shown in the images. The final color requires confirmation of the substrate, treatment, color standard and durability requirement.
No. The blue appearance in an image is not enough to identify a specific thread treatment. The treatment type, coverage, cure and performance must be stated in the technical specification.
A sample can be used for a preliminary review or replacement-part discussion. A dimensioned drawing or CAD file is preferred for critical fits and repeat production.
Provide a drawing, sample or BOM plus material, thread, head, drive, point, length, finish, quantity, inspection and packing requirements.
This page presents them as related custom screw directions, but each production order should identify the exact screw family. Machine-thread and self-tapping requirements should not be treated as interchangeable.
Prototype and small-batch production can be reviewed according to geometry, material, tooling, inspection and quantity requirements.
Repeat supply can be organized after the drawing, sample, material, finish, inspection plan, packing and revision are approved.
Part numbers, batch labels, revision marks and other identification requirements can be discussed when the marking method and location are defined.
Send your drawing, CAD file, sample or BOM to discuss custom CNC screws, precision machine screws and custom self tapping screws with project-specific head, drive, thread, point, material, finish, inspection and packaging requirements.
