QUALITY & TESTING
Inspection at the right stage.
A screw specification brings together dimensions, material condition and performance in the intended connection. Our quality pages explain what the different inspections examine.
See the equipment for dimensional measurement, drilling, hardness and corrosion evaluation, and discuss the test requirements for your product.
Inspection methods and acceptance criteria follow the agreed specification.
HEAD & DRIVE GUIDE
Specify the head and drive.
Use our catalogue illustrations to compare drive recesses, head profiles and under-head patterns. A clear description helps connect your drawing or sample with the configuration you need.
Browse the guide, then include the relevant head and drive details when you send an enquiry. Dimensions and application requirements complete the specification.
9 drive illustrations / 12 head styles / 12 under-head patterns
POINT & THREAD GUIDE
Choose the point and thread.
Point and thread descriptions help distinguish screws that can look similar at first glance. Compare the catalogue diagrams alongside the material and connection you plan to fasten.
Use the guide to describe a drill point, cutting feature or thread form. Send a drawing or sample where a name alone does not describe the configuration clearly.
Reference illustrations support an enquiry; they are not dimensioned drawings.
REPORTS & DOCUMENTS
Review the supporting records.
Review the Class 3 and Class 4 reports for named samples, together with the historical concrete-screw salt-spray record reproduced from our catalogue.
Each record belongs to its stated sample and test conditions. For a new enquiry, tell us which screw, finish and supporting documents you require so we can discuss the relevant information.
