High-strength latches

The new draw latches feature riveted mounting baseplates, that allow distributing loads over a large bearing area. Protex 43-3292, 43-4292, and 44-4292 latches are well suited for the industrial, earth-moving, and process equipment sectors.

The fasteners are compatible with Protex 40 and 41 series latches. They come in stainless or zinc-plated mild steel, reaching tensile strengths of 2,000 and 2,500 with type 04-4292 catchplates. All models have a standard grip range adjustment of 20 mm, and seal using lock wire or self-retaining pins. Both models can be padlocked for added security, while the 44-4292 is fitted with a side-action catch that locks when the latch is closed. The 43-4292 and 44-4292 models have an optional 150-mm long eyebolt, which increases the grip range adjustment of each product to 60 mm.

Tight or Not, This Bolt Tells

The VLI or Visual Load Indicator is a tension indicator built into the head of a bolt or stud. Reading the dial tells whether or not the bolt has reached its proper fastener load. If the bright yellow tension indicator stripe is hidden on the black face, clamp load remains assured within ±5%. If the yellow tension indicator stripe appears, the fastener needs maintenance. The advantages of VLI are that it gives maintenance personnel a quick visual tension check that can be performed at up to 30 feet away and greater distances with binoculars. VLI also provides indication of tension overload as well as under-load conditions. All fasteners are affected over time in service by temperature changes, joint relaxation, pressure fluctuations, and vibration. Adding this indicator to key wind-turbine fasteners significantly reduces scheduled time for maintenance and fixed costs while improving bolted joint safety and durability. The fasteners are approved by Germanischer Lloyd.
