Loos & Co., Inc.

Loos & Co., Inc. MS21260S6LH Wire Rope Locking Stud LH Thread 3/16 in

SKU CH-61Y0-NZ0S0

Stainless-steel locking stud swages 3/16 in rope with left-hand 5/16-24 thread for lifting, meeting MIL-DTL-781 and DFARS

  • Left-hand thread prevents loosening under vibration
  • 3/16 in rope compatibility covers common galvanised and stainless cables
  • Stainless steel construction resists corrosion in marine environments
  • MIL-DTL-781 qualified for critical lifting applications
  • DFARS compliant material sourcing for defence projects

LH-thread locking stud for 3/16 in rope

This left-hand thread locking stud is built for 3/16 in galvanised or stainless steel wire rope. It provides a secure swaged fitting for lifting and pulling assemblies where a left-hand thread is required. The stainless steel construction resists corrosion in harsh environments. It meets DFARS and MIL-DTL-781 standards for critical applications.

Thermals noise and power draw

As a passive mechanical component, the stud generates no heat, noise or electrical draw during operation. It relies entirely on the wire rope and attached hardware for load handling. There are no moving parts to wear or lubricate under normal use. Performance depends on correct swaging and installation torque.

Swaged fitting and compliance

The swaged outside diameter of 5/16 in and 3/4 in thread length define the mechanical interface for the assembly. DFARS compliance and MIL-DTL-781 qualification allow use in regulated defence and aerospace supply chains. The locking stud design prevents unintended rotation once installed. No additional software or accessories are included.

Questions about this item

How is the MS21260S6LH locking stud installed on the 3/16 in wire rope?

The stud is swaged onto the rope using a compatible swaging tool and dies matched to the 5/16 in swaged outside diameter. The step often missed is verifying the die set matches both the rope diameter and the stud shank before compressing.

What maintenance or replacement will the stainless steel swage fitting need over time?

Inspect the swaged joint regularly for cracks, corrosion or wire rope wear at the shank. Replace the stud if the swage shows deformation, the 5/16-24 LH threads are damaged, or the rope exhibits broken wires near the fitting.

What limit appears first when the locking stud is used for sustained lifting near its rated capacity?

The 3/16 in wire rope itself typically reaches its working load limit before the stainless steel stud or the 5/16-24 left-hand threads yield, making rope strength the governing factor.
