Product and application brief
A quarter-turn panel fastener uses a stud and matching receptacle to close or release an access panel through a short rotational action. The head alone does not identify the mating interface. Select and quote the matched assembly rather than treating its stud as an ordinary threaded screw.
Construction choices
| Choice or field | What to identify |
|---|---|
| Stud and head | Tool-actuated or hand-actuated forms are separate choices. Record the actual head, drive and stud-interface drawing. |
| Receptacle | Rivet-on, clip-on, snap-in and weld-on constructions occur in original-maker catalogues. Select the particular frame interface, not a generic interchangeable seat. |
| Retainer and accessories | A specified retainer can keep the stud with the panel. Grommets, springs and other accessories must be identified by the selected assembly documentation. |
Define the complete stack
Provide panel thickness, frame thickness and spacing, compressed gasket condition where relevant, receptacle mounting and every retainer or accessory. Original-maker selection documents use construction-specific stack calculations; a total thickness alone is not a universal stud-length formula.
Matched components, not name-based substitution
Identify the stud and receptacle series together. A similar head or nominal diameter does not establish engagement, retention or interchangeability. Proprietary catalogue names are references for construction only, not FastenerBridge brand affiliation or equivalent-part certification.
Quarter-turn versus captive threaded screw
A captive panel screw is retained at the panel but closes through a threaded connection. A quarter-turn fastening assembly uses its specified short-turn mating mechanism. Existing captive screw details remain a separate product choice.
Access, service and evidence
State head access, panel removal frequency, required captivity and service environment. Any requested vibration, cycle, sealing or retention evidence must cover the exact selected assembly. No universal torque, load, tool compatibility, service-life or aviation qualification is asserted.
Specification fields
| Choice or field | What to identify |
|---|---|
| Assembly identity | Stud, receptacle, retainer and accessory references or controlled drawings/revisions. |
| Stack and mounting | Panel/frame geometry, gasket condition, receptacle fixing and rear clearance. |
| Operation | Head and drive, opening/closing method and required captivity. |
| Order requirements | Material/finish requirements, service conditions, quantity and requested inspection evidence. |
Common product questions
Can a stud be chosen independently of its receptacle?
No. The selected stud, receptacle and accessory combination defines engagement and stack requirements.
Are quarter-turn fasteners the same as captive panel screws?
No. Captivity describes retention at the panel; it does not identify the closing mechanism.
Does the illustration prove a branded replacement will fit?
No. The generic illustration is not a mating-interface drawing or an interchangeability statement.
