• Forged from special C-1035 steel, fine grain, special bar quality.
• Spheroidized annealed for cold swaging.
• Sockets properly applied have an efficiency rating of 100%. This rating is based on the catalog strength of wire rope.

* Also available in 304 Stainless Steel: 1/4″ through 1-1/4″ open and closed

Muncy manufactures the Upson-Walton swage socket product line. Upson-Walton swage sockets range from ¼” wire rope to 3” wire rope, among the largest made in the world. Forged, we use special steel with mechanical and physical properties that enhance swaging, durability, and strength. For open swage sockets, the socket pin and cotter fit tightly into the socket’s ears for optimal surface contact for durability. We take pride when we manufacture our swage sockets, perhaps why we are among the largest producers of swage sockets in the world.

Boom Pendants, Structural, Lifting Device Applications
Upson-Walton swage sockets are used all over the world in many applications. Swage sockets are used in lattice type, or latticework boom cranes. Some crane manufacturers have specified swage sockets drilled for the next size rope for weight savings. Swage sockets can be found in bridges, stadiums, and many structures. Our sockets also come in stainless steel for certain applications.

Swage Socket Pins
Our swage socket pins are manufactured from select steel with proper chemical and physical properties. We machine our cotter pin holes to position the pin through the ears with a tight, yet practical fit. Muncy also offer socket pins with threaded ends for nuts and/or a cotter, also called a safety bolt, nut, and cotter pin.

Muncy manufactures the Upson-Walton swage socket product line. Our forgings use special steel with mechanical and physical properties that enhance swaging, durability, and strength. Upson-Walton closed swage sockets are sometimes used by themselves for specific pins, or in conjunction with our open swage sockets.

Upson-Walton Swage Sockets are Made in USA

Muncy manufactures its Upson-Walton swage sockets from material and forgings that we make in the USA. Muncy machines and performs its secondary processes in the United States. When you receive a swage socket with an “Upson-Walton” or “UW” on the forging, you can know with confidence it was made in USA.

Upson-Walton Sockets are easy to swage onto Wire Rope

Many of our customers tell us they like how our swage sockets swage onto wire rope. Our heat treat process is designed with the swaging process in mind, as the socket is subjected to extreme pressure between dies during swaging.

EFFICIENT, QUICK, and POSITIVE

Why pour zinc or epoxy when swaging is sure? Swage sockets have as much as five times longer life than spelter sockets.

Tests prove swage sockets have the best fatigue life

An extensive research study by one of the nation’s steel companies clearly established the fatigue life superiority of swaged sockets over other commonly used types of boom pendants. The tests included applied dynamic longitudinal load to the rope. They also simulated stresses which occur in pendant service. The graph at the right shows the results of these tests.
