Solderable SMT Nuts — Trade series (solderable SMT nuts)
Control electronicsM2–M5 threads secure shields and board-mounted brackets.
Instrument modulesOptional adhesive spots help hold the part during soldering.
Machine building & OEMThe clamping counter-face on studs and bolts throughout an assembly.
Steel fabricationBolted structural and frame connections.
Typical applications
soldering a fine threaded nut into a plated or non-plated board hole
selecting M2 through M5 for the mating screw
using taped-and-reeled placement in production
choosing with or without an adhesive spot
joints re-torqued at a service interval
completing a bolted joint on a stud, rod or bolt
Service conditions to specify against
Marine and coastal
Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
High load
Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.
Match the class
A nut below the bolt property class strips before the bolt reaches its own limit — pair class 8 nuts with 8.8 bolts, class 10 with 10.9.
Where to use something else
Do not size the nut from the screw alone; the board hole, solder land and reflow process must accept the part.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Manufactured to Trade series (solderable SMT nuts), Solderable SMT Nuts are nuts supplied by Engineering Hardware. The dimensional data, materials and selection notes are summarized here.
What Are Solderable SMT Nuts?
Solderable SMT Nuts are nuts defined by Trade series (solderable SMT nuts). They are selected by thread size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Common materials include carbon steel (typically zinc plated or hot-dip galvanized), alloy steel in property classes 8.8, 10.9 and 12.9, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, property class and surface finish appropriate to your load and environment.
Specification Guides
Each size, material and standard of Solderable SMT Nuts has its own reference page with the figures for that one configuration.
Solderable SMT Nuts are supplied to order. Pricing starts from approximately US$0.060 per piece for standard sizes in carbon steel; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.
Solderable SMT Nuts — Trade series (solderable SMT nuts)
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
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
