Assembly kit context
Representative Assembly Kits
These images show how separate fasteners, plates, brackets and support hardware can be grouped for RFQ. Himount supplies the metal parts made to drawings, not complete building systems.
Foundation and support fixing kits
Anchor rods, base plates, plate washers, nuts, gusset plates and matching installation hardware can be quoted as drawing-based kit groups.
Pre-installation hardware sets
Template plates, cable tray brackets, pipe clamp hangers, strut fittings and fastener sets help buyers understand how parts work together.
Custom bracket and stainless sets
Stamped brackets, stainless support hardware, embedded plates and formwork accessories can be matched by drawing, sample or specification.
Use these kit groups as a reference when sending drawings, sample photos, material, finish, quantity and target application.
Specifications
Key dimensions: Dimensions are confirmed from drawings or samples, including length, hole spacing, thickness, bore size, pitch, and end geometry where applicable.Thickness: Fastener diameter and length confirmed by drawing or standardMaterial / surface: Carbon Steel, Alloy Steel, Stainless SteelTolerance control: DIN / ISO / ASTM / custom by drawingRecommended surface finish: Zinc Plating, Hot Dip Galvanizing, Black Oxide, DacrometStandard / custom: Made to drawing / made to specification
Model / Standard Reference
China standard reference: matched against GB / GB/T or customer drawings when relevantLocal replacement reference: substitute codes can be reviewed from customer drawings or samplesInternational reference: ISO / DIN / ASTM / ANSI mapping is confirmed during RFQ reviewSample stage: English specifications can include tolerance, material, bore, hole spacing, and assembly notes
Surface Finish Notes
Available finishes: Zinc Plating, Hot Dip Galvanizing, Black Oxide, DacrometRecommended matching: Carbon Steel / Alloy Steel / Stainless Steel; select corrosion resistance, strength requirement, wear resistance, and assembly fit by applicationOutdoor or humid use: prioritize corrosion-resistant finishesThreaded or fitted parts: confirm coating thickness and assembly clearanceVisible or handled parts: confirm appearance consistency, cleaning, and anti-rust packing
