WebbTypes of self-tapping screws for plastics (Credit:stanleyengineeredfastening.com) Thread forming and thread cutting screws are available in flank angles of 30⁰, 40⁰, 45⁰, 48⁰ & 60⁰. Some brands also do dual spaced threads and trilobular shapes. Every matched pair of threads, external and internal, can be described as male and female. Generally speaking, the threads on an external surface are considered male, while the ones on an internal surface are considered female. For example, a screw has male threads, while its matching hole (whether in nut or substrate) has female threads. This property is called gender. Assembling a …

WebbRundown Torque Limits; Rundown Torque Limits. The friction between the screw and joint varies. This can cause the torque needed to run a screw down a thread, before engagement with the joint surface takes place, to vary as well. These effects could be, for example, hole interference, prevailing torque or varying lubrication.
