The Mooring Cleat (ASTM A743 CF8M / ISO 15085) is a marine casting cast to near-net shape by the lost wax process. The complete parameter table is below, together with the alloys the part is supplied in and the tolerances held.
What Is a Mooring Cleat?
The Mooring Cleat is a marine casting. It is selected by overall length together with the wall thickness and the hole or port geometry shown in the table below, and is supplied in a range of alloys and surface conditions to suit the service.
How This Part Is Cast
The part is cast to near-net shape with the boss faces and the fillets already formed, so machining is confined to the mounting faces and the hole pattern. Ribs and fillets are cast in rather than added, which is where the stiffness comes from at a lower weight than a machined or fabricated bracket of the same strength.
Alloy Options
The catalog specification calls for CF8M. This part is supplied in CF8M, CF3M, CA6NM, CB7Cu-1 (17-4 PH), CD3MN (2205), CE3MN (2507), Inconel 625 (CW6MC) and C95800 Nickel Aluminum Bronze. The alloy drives both price and lead time more than any other choice on the RFQ, so state it if your drawing calls one out — and if it does not, describe the service (the medium, the temperature and the pressure) and we will propose one.
Tolerances, Finish & Machining
As-cast dimensions are held to ISO 8062-3 DCTG 6-8 on a silica sol shell, which is roughly ±0.3 mm on a 50 mm feature and widens with size. As-cast surface finish is typically Ra 3.2-6.3 µm. A machining allowance of 1.5-3 mm is added to the faces called out on the drawing; every other surface is supplied as-cast. State the tolerance grade and the finish you need on the RFQ — both change the price, and a tolerance nobody asked for is the most common avoidable cost on a casting.
Inspection & Testing
Chemical composition by spectrometer on every heat, with the certificate supplied against the specified grade.
Dimensional inspection against the drawing, with a first-article report on new tooling.
Ferrite check on duplex grades, and confirmation of the heat-treatment condition that the seawater corrosion resistance depends on.
The Mooring Cleat is made to order. Pricing starts from approximately US$8.40 per piece for the smallest listed size in CF8M at production quantity; the final figure depends on pour weight, alloy, machining scope, surface finish and order quantity, and tooling is a separate one-time charge.

Inside the plant
Manufactured in our own plant
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Tooling & wax injection
An aluminum die is cut from your drawing or 3D model, and wax is injected into it under pressure. Everything downstream is a copy of this pattern, so the die is where the tolerance is actually decided — not on the shop floor afterwards.
First-article dimensional report on every new die before production wax is run.
02
Tree assembly & gating
Patterns are welded onto a wax runner to form a tree. How they are gated is not cosmetic: the gate positions decide which sections solidify last, and a heavy section fed from the wrong direction is where shrinkage porosity comes from.
Gating reviewed against the part's heaviest section before the first tree is built.
03
Ceramic shell building
The tree is dipped in ceramic slurry and stuccoed with refractory grain, six to eight times, drying between coats. The face coat is what the casting surface copies, which is why a silica sol face gives Ra 3.2-6.3 µm where a water-glass shell gives a coarser one.
Slurry viscosity and drying room temperature and humidity logged per coat.
04
Dewaxing
A steam autoclave melts the wax out fast, so that the wax — which expands more than the ceramic does — leaves before it can split the shell. Recovered wax is filtered and reused for gating rather than for patterns.
Every shell inspected for cracks after dewax; a cracked shell is scrapped, not patched.

Frequently Asked Questions
Which specification governs the Mooring Cleat?
The Mooring Cleat is cast to ASTM A743 CF8M / ISO 15085. The dimensions on this page follow that specification, and the material certificate supplied with the order is issued against it.
What sizes are available for the Mooring Cleat?
The table on this page lists 6 sizes for the Mooring Cleat by overall length, from 100 mm to 300 mm. Sizes outside the table are quoted on request — investment casting is tooled per part, so a new size is a new pattern die rather than a stock item.
Which alloys is the Mooring Cleat cast in?
The catalog specification calls for CF8M. The Mooring Cleat is supplied in CF8M, CF3M, CA6NM, CB7Cu-1 (17-4 PH), CD3MN (2205) and CE3MN (2507). The alloy drives both the price and the lead time more than any other choice on the RFQ, so state it if your drawing calls one out — and if it does not, describe the service (the medium, the temperature and the pressure) and we will propose one.
What wall thickness does the Mooring Cleat have?
The listed sizes run from 13 mm to 25 mm of nominal wall. Investment casting will hold a section down to about 1.5 mm in the silica sol shell used here — 0.6 mm on a small isolated feature — and the thin end of that range is a shell-filling question rather than a strength one. A section much heavier than the surrounding wall is the more common problem: it solidifies last and shrinks, so it is fed or cored rather than left solid.
How does the Mooring Cleat hold up in seawater?
The Mooring Cleat is supplied in grades chosen for permanent seawater exposure rather than coated for it — nickel aluminum bronze, CF8M or a duplex grade, depending on the load and the temperature. On duplex the ferrite balance and the heat-treatment condition are checked, because the corrosion resistance depends on both and neither is visible in the finished part.
How do I request a quotation?
Set the configuration on the technical drawing above — size, alloy, finish — and click "Request this configuration". The values carry into the quote form below it. Attach a drawing or a STEP file if you have one; it is the fastest route to a firm price, and it lets us flag any castability issue before you commit to tooling.
Guides for the Mooring Cleat
Each grade changes the price, the weight and what the part survives, so there is a page per grade for this part: CF8M (the catalog grade), CD3MN (2205) (roughly double the yield strength), Inconel 625 (CW6MC) (where duplex is not enough), C95800 Nickel Aluminum Bronze (the marine bronze), Ti-6Al-4V (Grade 5) (half the density, seawater immune) and CF3M (low carbon, for welded assemblies).
How it is shelled decides the tolerance and the surface you get, and the tolerance band is worked out against this part's own dimensions on each: Silica Sol Casting (DCTG 5 – 7, Ra 3.2 – 6.3 µm), Water Glass Casting (DCTG 7 – 9, Ra 6.3 – 12.5 µm) and Composite Shell Casting (DCTG 6 – 8, Ra 6.3 – 12.5 µm).
The specification and the testing change by sector more than the geometry does, so the mooring cleat is written up separately for Marine & Offshore, Oil & Gas and General Machinery.
If the question is still whether a casting is the right way to make this part at all, the Mooring Cleat application guide covers where it is used, what has to be decided before a price exists, and where investment casting is the wrong answer.
