CUSTOM BOLTS
Custom-Made Hex Head Bolts & Cap Screws
Custom-made hex head bolts and cap screws manufactured to customer drawings, samples and project-specific requirements.
DRAWING-BASED SUPPLY
Built around the approved requirement.
As a drawing-based custom hex bolt manufacturer, HOWIN reviews head geometry, under-head length, shank, thread, material designation and marking requirements before quotation. Dimensions and acceptance requirements are confirmed against the supplied drawing rather than a standard stock range.
HOWIN supplies custom fasteners rather than an off-the-shelf standard range. Final dimensions, material, quantity, lead time and documentation are confirmed during quotation.
