Double end threaded studs are essential in structural applications where two components need to be securely fastened together with threaded connections on both ends, ensuring stability and strength. They are available in left & right-hand threading variants. The right-hand threading provides compatibility with standard fastening systems for easy fastener installation and replacement, while the left-hand threading provides reverse fastening motion to avoid unintentional loosening. They feature aluminium construction for a high strength-to-weight ratio and their plain finish offers easy integration with different materials. They are further classified into hex and round shank types. The hex shank design minimises the risk of slippage or stripping, while the round shank provides enhanced alignment and versatility during installation and can withstand higher torque loads.

Double End Threaded Studs
Double-end threaded studs or rods have threading on both ends and an unthreaded portion at the centre. They are used as connecting rods to join threaded components with different thread sizes in construction, plumbing, metal fabrication and repair applications. Raptor Supplies offers double-end threaded rods from brands like Grainger and TE-CO. Double-end threaded studs can also be bent to act as specialised fasteners like anchor bolts or U-bolts.
Working Mechanism
- To use a double end threaded stud, first, join the surfaces prepared by drilling holes to match the diameter of the stud.
- Insert the stud through the holes with the threaded ends protruding from each side.
- Thread the nuts onto both ends of the stud and then tighten evenly with a wrench or socket.
- The pressure (applied by the nuts) squeezes the surfaces together, creating a tight and secure joint.
Features
- Double-end threaded studs have threads on both sides to resist loosening due to vibration and to attach a nut.
- They can be installed in a tapped hole with a nut or washer on the other end for clamping a fixture onto the surface.
- Double-end threaded studs are generally stronger than a standard bolt for fastening applications.
- They have an unthreaded middle section for gripping & adjusting the connection.
- They can be used to connect parts having coarse threads to other parts having fine threads or parts with right-hand direction threads to parts with left-hand direction threads.
- Selected models have a hex drive for ease of installation and an unthreaded tip for threading into nuts easily, thereby preventing damage to the threads.
TE-CO Double-End Threaded Studs:
- These double-end threaded studs are available in Imperial & Metric threads with Class 2A thread fit.
- Most of these threaded rods have a round shank, but some have a square shank for secure holding during installation.
- They have steel (with black oxide finish) or stainless steel construction.
- These studs can have equal or unequal threaded lengths on both sides of the shank for use in specific applications.
Frequently Asked Questions
What is the use of hollow threaded rods?
The hollow centre of these rods allows their use as a vent, axle or passageway for wiring connections.
Can these double-end threaded studs be used on wood?
Yes, wood screw-threaded studs or hanger bolts are used to hang / mount / attach parts to wooden structures. Wood-to-wood joining studs, also called dowel screws, are suitable for joining two wooden pieces.
Can we reuse double-end threaded rods once removed?
Yes, double-end threaded studs have durable threads on their ends for installation & removal multiple times.
What standards do double-end threaded rods abide by?
These double-end threaded rods adhere to international standards like DIN (German Institute for Standardisation) and ASTM (American Society for Testing and Materials) for meeting material quality standards and dimensional requirements.
How do a fully threaded double end threaded stud and a partially threaded one differ from each other?
A fully threaded double end threaded stud has threads along its entire length, while a partially threaded one has threads only on the ends.
How to determine the length of a double end threaded stud?
The length of a double end threaded stud is determined by measuring the distance between two objects being connected and adding enough length to allow for the installation of nuts on both ends.
