Transport equipmentKnurled or wing heads allow tool-free service at selected positions.
Aircraft and vehicle panelsQuarter-turn fasteners release service panels without loose screws.
Transport & bodyworkTrailer, bus and van panels joined blind from one side.
Signage & claddingFast, vibration-resistant fixing of thin material.
Typical applications
matching length code to the total panel stack
selecting a receptacle with the required adjustment
choosing a slotted, flush or wing head for service access
locking a captive panel stud with a 90-degree turn
blind fixing where only one side can be reached
riveted pivots that must stay tight but still turn
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.
Where to use something else
Do not mix a stud and receptacle from different length or adjustment families; the quarter-turn can appear locked without clamping the panel.
Not for a joint that has to come apart in service — removal means drilling the rivet out.
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.

Quarter-Turn Panel Fasteners (Trade series (quarter-turn panel fasteners)) are a type of rivets used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Quarter-Turn Panel Fasteners?
Quarter-Turn Panel Fasteners are rivets defined by Trade series (quarter-turn panel fasteners). They are selected by nominal diameter 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), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.
Quarter-Turn Panel Fasteners are supplied to order. Pricing starts from approximately US$0.12 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.
Quarter-Turn Panel Fasteners — Trade series (quarter-turn panel fasteners)
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.
