Reliable Screw Lock Spring Hooks for Demanding Environments
When securing equipment around a 4WD, caravan, camper trailer or boat, a reliable connection is essential.
Dunn & Watson 316 Stainless Steel Screw Lock Spring Hooks feature a threaded locking sleeve designed to reduce the possibility of accidental gate opening, providing additional security over traditional non-locking carabiner clips.
These versatile stainless steel fittings are ideal for general-purpose attachment, equipment organisation and compatible chain or cable connections.
Marine Grade Stainless Steel Built to Last
Manufactured using 316 stainless steel, these locking spring hooks are designed to withstand exposure to moisture, humidity and coastal conditions.
Unlike standard plated steel fittings that can develop surface corrosion, 316 marine grade stainless steel offers excellent resistance to rust and chloride-related corrosion, making it a practical choice for boats, outdoor equipment, 4WD accessories and caravan hardware.
Spring-Loaded Gate with Threaded Locking Sleeve
The screw lock design provides the convenience of a traditional snap hook with the additional security of a threaded gate locking mechanism.
Once the spring-loaded gate is closed, the knurled locking sleeve can be tightened to help prevent the gate from opening unintentionally.
The clip can be unlocked and removed by hand whenever accessories need to be repositioned or disconnected.
Choose from Three Practical Sizes
-
Light Duty – 60mm: Compact locking clip for smaller accessories, camping gear and equipment organisation
-
Medium Duty – 100mm: Versatile general-purpose option for 4WD, caravan and marine hardware connections
-
Heavy Duty – 160mm: Larger locking spring hook for bulkier attachment points and general-purpose equipment connections
