Industrial screws
Search the published products below or start an RFQ for another screw type. Final supply is controlled by the buyer-approved standard, drawing or sample—not by a catalogue name alone.
Final head and drive, thread and point, drilling capacity, substrate stack, material, hardness, finish, washer, packing and documents follow the buyer-approved quotation.

Buying & RFQ guide
A screw name alone is not enough. Use these fields to receive a comparable, specification-controlled quotation.
Identify the quotation basis and installation conditions.
XHT reviews screw projects against buyer-controlled input.
Specification control: DIN 7504 is a withdrawn legacy designation. ISO 15480:2019 may apply to specified steel K-type self-drilling screws, but stainless materials, sealing-washer assemblies, drilling capacity, corrosion resistance and roof-sealing performance require separate buyer approval. Commercial names and standards are not automatically interchangeable.
Screw RFQ
Attach a drawing, product list, photo or sample reference. Mark every field that must not be substituted. Testing, certificates, traceability, corrosion performance and packing apply only when written into the quotation and order.
