Define each custom screw-and-nut combination by its head geometry, thread dimensions and selected material requirements.
Select the screw head and matching hardware
The example shows broad transverse, T-like heads with nuts and washers. Hex, flange and round heads are distinct requested forms; multiple sizes require individual dimensions rather than assumptions from one photograph.
Specify material and thread separately
Carbon steel, high-strength steel and stainless entries offer selection directions. Numeric steel classes and grades SS304/SS316 are not interchangeable, while passivation suitability depends on the selected material.
- Identify the screw head and installation clearance.
- Dimension shank, bearing seat and engagement.
- State metric or inch thread series and pitch.
- Select nuts and washers for the actual connection.
- Agree finish and required acceptance documents.
Confirm the custom supply proposal
Provide quantities and application conditions for review. Chinese manufacturer source wording alone does not verify Relia manufacturing identity, origin or authorization, and appearance does not prove strength or corrosion performance.
