Inserts & Studs : Ring Locked Studs

Ring Locked Studs

Alcoa Fastening Systems & Rings ring locked studs were designed to transfer high axial loads into weak base materials. A lockring prevents the stud from backing out, in either soft or hard materials, as it resists extremely high torque loads.

Variations of these studs include hydraulic, terminal types, full shank, reduced-shank nut ends, and studs designed for installation into extremely hard materials.
A complete line of oversize replacements are available, if required.

Variations of these studs and lockrings are made in a variety of materials and finish combinations. Standard thread sizes are available from 0.138 to 1.000 (inch) and 5 to 24 (millimeter). Ring locked studs are covered by “DOD”, “MS” ("AS"), “DIN” and “LN” standards.
