Property Class 8.8 Steel Inch Left-Hand Fully Threaded Rod

Applications & Industries

Where Inch Left-Hand Fully Threaded Rod are used, and what decides the specification in each case. Stocked from 6-32 to 1/2-13 (screw size).

Industries that specify Inch Left-Hand Fully Threaded Rod

• Opposed adjusters Left-hand and right-hand rod pairs used to change length without disconnecting the joint.
• Rotating equipment Threaded adjustments arranged to resist self-loosening in service.
• Machine fixtures Inch adjustment rods where the thread hand is part of the mechanism.
• Repair and fabrication Replacement rod matched to existing left-hand nuts and couplers.
• Pressure equipment & flanges Studs and nuts on flanged joints, where both ends are tightened and the assembly is inspected.
• Plant & machine installation Anchoring and levelling machines onto bases and frames.

Typical applications

• providing a left-hand threaded member for an opposed adjuster
• matching the rod to a left-hand nut rather than a standard right-hand nut
• holding a threaded adjustment against rotation in a paired mechanism
• specifying inch thread class, hand, length and material together
• clamping a joint from both ends where a headed bolt will not fit
• suspending services from a soffit on threaded rod

Service conditions to specify against

Marine and coastal

Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.

High load

Supplied in ISO 898-1 property classes, so the joint can be designed to a stated proof load and tightened to a calculated torque rather than by feel.

Where to use something else

• Do not pair a left-hand rod with an ordinary right-hand nut; the threads will not engage correctly.
• Not for a joint that must be tightened from one side only — there is no head to hold.
