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.

Custom special alloy hex bolts manufactured to customer drawings

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.
