Guide to Essential Industrial Screw Types
Different screw types, from machine screws to self-tapping varieties, are engineered for specific materials and joining requirements.
Understanding the application
Socket cap screws, countersunk screws and self-tapping screws serve different head-clearance and mating-material requirements.
Selection & technical considerations
Machine screws engage a compatible tapped thread; self-tapping screws require a suitable substrate and pilot hole. Drive style and head seating must fit the assembly.
Practical checks before use
Specify standard, thread, length, material, grade and finish. For a flush head, include the matching countersink geometry.
A complete enquiry includes
- Product type and reference standard or approved drawing
- Thread diameter, pitch, length and dimensional requirements
- Material, property class and specified surface finish
- Quantity, inspection documents and delivery destination
