Custom Stainless Steel Boat Parts
SHENZHEN BENXIN ELECTRONIC HARDWARE CO., LTD
Product Details
Precision machined marine parts and custom boat fittings in 316L stainless steel: CNC turned and milled components, machined from bar or tube, for marine equipment and boatbuilders.
Keywords: precision machined marine parts, custom boat fittings, stainless steel marine hardware, marine CNC machining, boat parts manufacturer
Product Overview
Below the waterline and above it, boat reliability comes down to hardware. Our precision machined marine parts — cleats, thru-hull fittings, shaft components, valve bodies, brackets and custom adapters — are CNC machined from 316L stainless steel bar or tube, then deburred, passivated and inspected so they survive years of saltwater service. We machine to drawing for boatbuilders, marine equipment OEMs and distributors worldwide.
Key Features
- 316L stainless material — molybdenum-bearing grade for seawater and spray zones
- CNC turning & milling — complex geometries machined from bar, tube or forging
- Tight tolerances — critical sealing and mating surfaces held to drawing tolerance
- Passivated surfaces — restored passive layer for maximum corrosion resistance
- Deburred, clean finish — no sharp edges, ready for installation
- Custom threads — NPT, BSP, metric and marine-standard threads gauged per order
Applications
Used for thru-hull fittings, deck hardware, cleats and chocks, rudder and shaft components, valve and manifold bodies, exhaust flanges, sensor mounts and custom brackets on yachts, commercial vessels and offshore equipment.
Manufacturing & Factory Capability
Our precision machining capability is built for marine-grade work:
- CNC lathes & machining centers — turning, milling, drilling and tapping in one facility
- Bar & tube stock program — 316L bar and tube held in-house, including drawn tube for hollow parts
- Secondary operations — thread cutting, slotting, keyways and cross-drilling
- Surface treatment — passivation, electropolishing and bead blasting available
- 100% critical inspection — threads, bores and sealing faces verified with calibrated gauges
- Batch traceability — material heat numbers recorded per order
Customization & OEM/ODM
Send your drawing or sample: we provide DFM feedback, prototypes and volume production. Both OEM (your design, your brand) and ODM (we refine the design for manufacturability) are supported, with private packaging for distributors.
Quality Assurance
Threads and critical dimensions are 100% inspected on marine safety parts; first-article inspection reports issued before production runs. Material certificates available on request.

Frequently Asked Questions
Yes. We provide OEM/ODM custom manufacturing from your drawings in PDF, DWG, STEP, IGES or STL formats.
- What materials can you machine?
Aluminum, stainless steel (304/316), titanium alloy, copper, brass, POM, PEEK and other engineering plastics. - What is your tolerance standard?
General tolerance ±0.05mm, tight tolerance down to ±0.005mm upon request. - Can you provide material certificates & inspection reports?
Yes, 3.1 material cert, FAI, CMM inspection report are available. - What is your lead time?
Sample: 3–7 working days. Mass production: 7–15 working days, depends on complexity & quantity. - Do you support small batch & prototype orders?
Yes, we welcome prototype, low-volume and custom one-off parts. - What surface finishes can you offer?
Anodizing, sandblasting, passivation, polishing, powder coating, laser marking, deburring. - How do you handle shipping?
We support DHL, FedEx, TNT, sea freight, and can do DDP / DAP terms.
- Is there a minimum order quantity (MOQ)?
We have no strict MOQ. We accept prototype trial orders as low as 1 piece. - How can I get an accurate quotation?
Please send us your 3D STEP/IGES file, 2D drawing with tolerance, material requirement, quantity and surface finish. - Can you help with DFM optimization?
Yes. Our engineers provide free DFM suggestions to reduce machining cost and improve manufacturability. - How long is the quotation valid?
Quotation is normally valid for 30 days, subject to raw material price fluctuation.
Pricing depends on material, dimensions, tolerance, quantity and surface finish. Please send your drawings (PDF/DWG/STEP/IGES) and we will provide an exact quote, usually within 24 hours.
The price is based on material cost + machining time + surface treatment + tooling (if any) + packaging and freight.
Our standard quotes are FOB Shenzhen/Dongguan unless otherwise stated. Air or sea freight can be quoted separately according to your destination.
Our price reflects the material grade, tolerance level, full inspection and finishing quality. If needed, we can suggest cost-saving design changes (e.g. relaxing non-critical tolerances) to reduce the cost.
Yes. We provide tiered pricing — the unit price decreases as the quantity increases. Please tell us your target quantity for the best price.
