Techniques for stripping pigtail threads
Mixing metric and imperial fasteners, or pairing coarse-thread bolts with fine-thread nuts, is a reliable way to strip threads. The components may appear to fit initially but will fail under load. Stripped. Has a stripped thread ever left you staring at a half-finished project, wondering if it's ruined for good? I've felt that same frustration when a simple bolt or screw refuses to grip, turning a quick fix into a major headache. However, this clamping action causes stress on the fasteners, which can lead to disastrous material failure if not. Thread stripping or shearing of threads is a common problem. Here Dr Bill Eccles – from Bolt Science – explains how thread stripping occurs and how the BOLTCALC program was recently used in a case study to solve a thread stripping problem. Thread stripping is gradual in nature and hence is not. To fix stripped threads on a bolt, you generally have a few options depending on the severity: for minor damage, you can use a thread restoring file or a die to reshape the existing threads. It allows you to create new threads within a damaged hole by inserting a coil that mimics the original threading.

Fiber Optic Cable Hot Joint Connection Method
A fusion splicer is a specialized tool used in fiber optic networks to join two fiber optic cables together permanently. It works by applying heat to the ends of the cables, causing them to melt and fuse together. This method is flexible, simple, convenient, and reliable, commonly used in building computer network cabling. The typical attenuation is 1dB per connection. It allows connections. Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear. They may be used to convey voice, video and data. Common connector types are named FC, SC and LC for single-mode applications and ST for multimode, but there are also dozens of other types, with special qualities such as duplex connections, particularly small. This blog post looks at the various options available to installers for responding to these issues; from splicing and field-fit connectors to factory-terminated or pre-connectorization.
