Clevises are U-shaped fasteners that are used with a clevis pin to connect to a tang or clevis mount. Clevis fasteners are used to connect products such as cylinders, trailers and structural members subjected to tension loads only. Clevis fasteners are used in many industries, such as agriculture, marine, aerospace, construction, and manufacturing.
...on its axis, the spindle head starts rotating to the point of forming a hole of a specified diameter. The spindle head incorporates a mechanism with inner and outer eccentric bodies. Their arrangement facilitates mutual rotation to maintain the tool...

Connection Heads

(58 companies)
Connection heads, also referred to as thermoheads or thermocouple heads, provide a means for connecting temperature sensors and extension wires.

Fusible Alloys

(14 companies)
Fusible alloys have low melting points, usually below 300 o F. Many fusible alloys have eutectic compositions. Fusible alloys are used as work holders, electroforming mandrels, tube bending aids, fire sprinkler parts, steam boiler relief plug, resin casting or potting molds, fuse parts, thermostat components, switch parts, thermal management products, lens blocking alloys, and wax pattern injection dies.
Riveters and riveting machines insert fasteners through aligned holes in parts to be joined, then press or hammer them from the insertion side to provide the second retaining head.

Tank Heads

(23 companies)
Tank heads are the end caps on cylindrically-shaped pressure vessels. They generally comply with ASME standards or similar codes because of the high pressures they must withstand for use with gas storage tanks, driving cylinders, distillation towers, and reactors.
