The H-Lift Stainless Steel Rigging Screw Jaw/Jaw type is a highly durable wire rope tensioning device featuring a closed tubular body and two clevis ends, designed to securely adjust and maintain tension in architectural and marine rigging systems.
Features two traditional jaw (clevis) fittings equipped with removable pins, allowing for quick and secure attachment to fixed anchor points, pad eyes, or wire rope thimbles without the need for extra connecting hardware.
Designed with a sleek, closed tubular body (often referred to as a bottlescrew) that protects the internal threads from dirt and debris while providing a streamlined, aesthetic appearance compared to open-body turnbuckles.
Manufactured from premium marine-grade stainless steel (such as AISI 316), delivering exceptional resistance to rust, corrosion, and harsh weather conditions in coastal, saltwater, and outdoor environments.
Available in a comprehensive range of metric thread sizes, providing easy and precise length adjustment to safely tension cables, balustrades, and structural stays across various load requirements.
Marine Grade 316 | Closed Tubular Body | Precision Tensioning
The Stainless Steel Rigging Screw (Jaw & Jaw) is a premium tensioning device featuring a sleek, closed tubular body that protects its internal threads. Equipped with opposing jaw (fork) ends and removable clevis pins, it provides incredibly fast and secure connections for tensioning sailboat shrouds, architectural wire balustrades, shade sails, and heavy-duty industrial lashing.
⚠️ SAFETY WARNING: NOT FOR OVERHEAD LIFTING. These commercial-grade rigging screws are designed exclusively for tensioning wire ropes, structural stays, and static loads. They are NOT rated, calibrated, or certified for overhead lifting or life-safety fall-arrest applications.
🪝 Dual Jaw End Fittings
Features opposing jaw (fork) ends equipped with removable clevis pins. This design allows for incredibly fast, secure connections directly to anchor plates, eye bolts, rings, or wire rope thimbles without needing additional shackles.
🛡️ Closed Body Design
Unlike open-frame turnbuckles, a rigging screw features a sleek, tubular closed body. This encapsulates the threads, protecting them from dirt, impact damage, and snagging, making it ideal for permanent installations where aesthetics matter.
📏 Precision Tensioning
Rotating the central tubular body draws the left-hand and right-hand threaded jaws inward simultaneously. This provides smooth, highly precise tensioning for cables, wires, and architectural rods.
🌊 Marine-Grade Durability
Constructed from premium 316 marine-grade stainless steel. This provides maximum corrosion resistance against saltwater, severe weather, and industrial chemicals. Available in polished or matte finishes.

Q: What is the difference between a Rigging Screw and a Turnbuckle? [Image comparing a sleek closed-body Rigging Screw side-by-side with an open-frame Turnbuckle] A: The primary difference is the body design. A Rigging Screw has a closed, tubular body that hides and protects the threads, offering a sleeker architectural look and preventing snags. A Turnbuckle (or bottlescrew) has an open frame, which leaves the threads visibly exposed for easy inspection, cleaning, and lubrication.
Q: How do I attach wire rope to a Jaw/Jaw rigging screw?A: Because the jaw has a removable pin, you can create a loop at the end of your wire rope (using a thimble and wire rope clips, or a hand-spliced eye). Once the loop is made, simply remove the clevis pin from the jaw, slide the wire loop into the fork, and securely re-insert the pin.
Rigging Screws vs. Turnbuckles
Guide to Tensioning Devices for Marine & Construction
Rigging screws and turnbuckles are essential components used to adjust tension and secure loads. While they serve similar functions, their distinct designs make them suitable for specific applications.
Rigging Screws
*Rigging screws feature a pipe-like closed body encasing the threads.
Definition: Also known as rigging tensioners, these devices adjust tension in cables, wires, or rods. They typically feature a closed body (tubular) design.
Functionality: Rotating the body causes the attached fittings (different handed threads) to move in or out, providing precise tensioning.
Best Use: Critical for maintaining correct tension in shrouds, stays, and guard wires where protection of the threads is beneficial.
Turnbuckles
*Turnbuckles feature an open frame allowing view of the threads.
Definition: Often called bottlescrews, these mechanical devices consist of an open frame with two threaded ends connected to eye bolts, hooks, or jaws.
Design: The open body allows for easy visual inspection, lubrication, and maintenance. Available in stainless steel, bronze, and galvanized steel.
Functionality: Features one left-hand and one right-hand thread. Rotating the central frame adjusts both ends simultaneously.
Applications: Widely used in marine rigging, construction, and general tensioning.
Key Differences Summary
Body Design Rigging screws generally have a closed (tubular) body, protecting the threads. Turnbuckles have an open body, allowing for inspection.
Thread Types Rigging screws typically use different handed threads on each end for fine adjustment. Turnbuckles use standard LH/RH threads for rapid adjustment.
Usage Context Turnbuckles are preferred where frequent adjustments and inspection are needed. Rigging screws are often preferred for permanent installations where aesthetics or thread protection is prioritized.
