Standard parts in this family
What can be changed on a hose & band clamp
- Dimensions — lengths, diameters and head sizes outside the standard table.
- Thread — fine pitches, left-hand threads, partial threading, non-standard thread lengths.
- Material — grades the catalog part is not stocked in, up to and including the customer's own specified steel.
- Strength class — a higher property class than the standard part, where the material and heat treatment allow it.
- Finish — plating, passivation or coating to a salt-spray requirement rather than to a default.
- Head and drive — a drive that is not in the standard, or a head form specific to the assembly.
- Marking — part numbers, logos or traceability codes on the head.
Order terms
- Minimum order
- 2,000–5,000 pieces. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed.
- Samples
- Within 7 days of drawing approval.
- Drawing
- Preferred, but not required — a sample, photographs or a sketch is enough to start.
What a quotation needs
Nine things, and a drawing settles most of them at once. Where a field is unknown, say so — an assumption stated is better than a blank, and several of these can be recommended rather than specified.
- Drawing
- A 2D drawing (PDF or DWG) or a 3D model settles almost every other question on this list at once.
- Dimensions
- Diameter, length, head size and any features — enough to know what is being made.
- Tolerance
- Tolerance is the single biggest cost driver. Tell us which dimensions are critical and which are not — holding everything tight costs money on features nobody measures.
- Material
- Carbon steel, alloy steel, stainless, brass, aluminium, titanium — or the application, and we will suggest one.
- Strength grade
- Property class to ISO 898-1 (8.8, 10.9, 12.9) or stainless class to ISO 3506 (A2-70, A4-80). This decides the material and the heat treatment together.
- Thread standard
- Metric coarse, metric fine, UNC, UNF, BSW or a pipe thread — and the tolerance class if it is specified.
- Surface finish
- Zinc, hot-dip galvanised, black oxide, Dacromet, Geomet, nickel, passivation, or plain. Salt-spray hours if you have a requirement.
- Quantity
- Annual volume and first-order quantity. Volume changes which process is the right one, so it changes the price more than most buyers expect.
- Application & environment
- What the part holds together, and what it has to survive — temperature, vibration, chemicals, salt. This is what lets us catch a specification that will not work before it is made.
No drawing?
Most replacement parts arrive without one. None of these routes is a problem, and all of them end with a drawing produced for your approval before anything is cut or formed.
- A physical sample
- The most reliable route. The part is measured, the thread and finish identified, and a drawing produced for your approval before anything is made.
- Photographs with a scale
- Photographs against a ruler or a caliper, ideally with a thread pitch gauge reading. Enough to identify a standard part or to start a drawing for a non-standard one.
- A hand sketch
- A sketch with the dimensions that matter is a perfectly good starting point — the drawing gets made from it and comes back to you to check.
- The assembly it goes into
- Sometimes the fastener is wrong in the first place. If the joint is described rather than the part, a better part can be proposed.
Questions
What is the minimum order quantity for a custom part?
Between 2,000 and 5,000 pieces for most parts. The exact figure depends on the part: it is set by the tooling the drawing calls for, and is confirmed when the drawing has been reviewed.
How long does a sample take?
Within 7 days once the drawing has been approved. The drawing stage comes first, and for a part being reverse-engineered from a sample it is where most of the time goes.
Can you make a part without a drawing?
Yes. A physical sample, photographs against a scale, or a dimensioned sketch are all workable starting points. A drawing is produced from whichever of those you have and sent back for approval before anything is made.
Send the part
A drawing answers most of this at once. If you do not have one, fill in what you know and attach a photograph — samples follow within 7 days of the drawing being approved.
