Rivet Nut Tool Manufacturer | Torchmark Ningbo Factory
Torchmark is a Ningbo manufacturer of rivet nut tools and inserts: hand rivet nut guns, M3-M12 tool kits, and accessories for sheet-metal assembly.
Rivet Nut Tools Made in Ningbo
Torchmark designs and manufactures rivet nut tools and accessories at our Ningbo, Zhejiang factory, supplying distributors and importers with hand rivet nut guns, insert tool kits and spare mandrels for sheet-metal and thin-wall assembly.
What We Produce
Our rivet nut range covers manual hand rivet nut tools, 13-inch rivet nut guns for M3–M12 inserts, complete tool kits, and the mandrels, noses and jaws that keep them running. Custom tooling and private-label printing are supported.
Manufacturing & QC
Tool bodies are machined and heat-treated in-house, then checked for thread fit and pull performance per lot. Inspection records are available on request with your order.
Specifying a Rivet Nut Tool Range
A rivet nut tool range is defined by thread coverage, grip range and consumables — not by how many tool bodies are in the catalogue. Buyers who specify those three things end up with a range that actually covers M3–M12 assembly work.
Thread coverage and nose pieces
List every thread size the range must set, then map the mandrels and nose pieces needed for each. A gap in mandrels is more common than a gap in tools. The M3–M12 distributor guide shows the usual coverage.
Grip range and hole tolerance
Spin-out is usually a hole problem, not a tool problem. The size chart gives the hole size per thread; include the punch and a go/no-go gauge in the kit so the end user can verify it. Grip range must bracket the actual material stack.
Tool type and stroke control
Hand lever tools suit occasional use; pneumatic or spin-pull tools give repeatable stroke for volume. The manual vs pneumatic comparison covers the trade-off. Mandrels are wear items — stock them with the first order.

Questions Buyers Ask Before Ordering
What is in a starter kit?
Tool, full mandrel and nose-piece set for the stated thread range, a nut assortment and a hole-size chart. A pre-built kit removes the guesswork for a first order.
How do we diagnose spin-out?
Check hole diameter and burrs first, then grip range, then stroke. The complete guide has a failure-mode section with inspection criteria.
Can you supply inserts as well as tools?
Yes, tools, inserts and accessories are usually ordered together so the range is complete on arrival.
What documentation is available?
Dimensional inspection methods, material declarations and test reports are available on request for a named SKU; we do not publish unverified capacity or certification claims.
