The KS-1938T Speed Wing Nut is a solid stainless steel 3/8"-16 nut with integrated wings for fast hand-tightening and a hex top for 19 mm wrench operation. It is built for rigging assemblies that are adjusted often, including couplers, speed rail hardware, suction-cup rigs, and car-rigging systems.
Why It Matters
A fast nut should still work when the hardware is crowded. The off-center wings let adjacent speed wing nuts sit closer together, while the hex top keeps a tool option available when hand force is not enough.
Key Features
3/8"-16 thread matches a common rigging fastener size.
Solid stainless steel construction resists corrosion and repeated handling.
Hex top accepts a 19 mm wrench for tool-assisted tightening.
Off-center wing design helps adjacent nuts fit in confined rigging layouts.
Applications
Use for car-rigging systems, coupler assemblies, speed rail details, suction-cup rigs, and hardware that needs repeated adjustment or disassembly.
Compatibility
Designed for 3/8"-16 threaded fasteners; sister speed wing nuts cover M10, M12, 1/2"-13, and 3/8"-16 applications.
Frequently Asked Questions
Can I tighten it with a wrench?
Yes. The hex top fits a 19 mm wrench when hand tightening is not enough.
Why are the wings off-center?
The offset helps two speed wing nuts sit close together without the wings clashing.
