Steel spring clamp set

A three-size set of steel spring clamps, where temper and jaw alignment matter more than a matched photo.

What this product is

Spring temper is the hidden variable in a set of three steel spring clamps that look identical in a photo. Potential relaxation shows up after the jaws have been opened and closed, when a clamp that felt firm on day one no longer holds a board. Typical three-piece sets sit in an estimated band of about 2.2 to 4.8 dollars at 500 sets, with an indicative retail span of 15 to 26 dollars. Measure closing force on each size against the approved sample, and look for jaws that twist instead of meeting flat. Vinyl pads that slide on smooth stock are a separate complaint from a weak spring. Plating that chips at the pivot will rust in a damp toolbox, so a humidity note belongs in the spec if the destination is damp. Customization is usually a grip color, a size mark, and a retail sleeve. Changing the wire diameter is a new tool, not a colorway.

Indicative sourcing numbers

These are desk estimates for a conversation, not a factory invoice and not a retail offer from this website.

Indicative China sourcing price: $2.20 to $4.80

Indicative estimates only. Actual margins vary by supplier, quantity, specifications, shipping, duties, taxes, marketplace fees, advertising and destination market.

Why it is interesting

Clamp sets are a standard wire-form export, so the useful comparison is temper and jaw match across the three sizes.
A sleeve and a grip color brand the set without a new spring design.

What to specify

Set: Three steel spring clamps of different sizes
Force: Closing force compared with the approved sample
Jaws: Pads or bare steel; jaws should meet flat
Finish: Plating or paint agreed at the pivot
Pack: Sleeve or hang card for the set of three

Customization and private label

Grip color, a size mark, and a retail sleeve are common; a new wire diameter or jaw forging is a different tool.

Some customization is realistic on this kind of product. Private label packaging is often possible once artwork is approved. Read how private label manufacturing in China is handled, and when a new product needs the OEM/ODM path.

How the desk would source it

Note 1. Cycle each size and recheck holding force, because a fresh clamp can feel firm before the temper relaxes.
Note 2. Confirm the order counts sets of three so a unit-price quote is not mistaken for a single clamp.

The usual path is the same as other China factory sourcing: confirm the spec, compare factories, sample, then inspect before shipment. China supplier verification and China quality inspection are available. Goods can be received at the Xiamen warehouse and moved through China warehouse consolidation or sea, air, and express freight.
