Fastener screws are an indispensable type of connector, renowned for their versatility and dependability. Typically constructed from a combination of screws and nuts, these fasteners are essential for uniting plates, thin-walled components, and even for applications like pipelines. Below, we delve into the comprehensive details of fastening screws:
1, Specification and size
• Diameter: Often denotes the inner diameter of the thread, which is crucial for ensuring compatibility and is typically measured in millimeters (mm).
• Length: This measures the full length of the screw, a vital aspect in accommodating various applications, and is usually recorded in centimeters (cm).
• Thread quantity: This specifies the number of threads along the screw, playing a pivotal role in determining the screw's usable length, strength, and additional functional characteristics.
2, Thread specifications
Ordinary thread: Features a wide pitch designed to easily generate anti-slip grooves on both sides of the thread, enhancing both twisting force and connection integrity.
Fine thread: With a more refined pitch, its thread top is smoother, minimizing slip risks, thus boosting the connection's tightness and reliability.
3, Common types
M6 screw: Known for its remarkable versatility, this screw can pair with various heads, such as small countersunk and semi-circular, to deliver distinct results.
Small countersunk screws: Although they insert seamlessly into grooves, their minimal force surface poses a potential loosening risk.
Half round head screws: Ideal for completely covering fasteners' anti-slip patterns, they offer sturdiness and security when tightened.
Stainless steel fastener screws: Noted for their corrosion resistance and high strength, they come with a slightly higher price tag but offer exceptional durability.
4, Selection factors
When selecting fastener screws, it's essential to evaluate the following factors:
The material and thickness of the objects to be joined.
The configuration and dimensions of the connecting objects.
The specifications, dimensions, and thread types of the intended fastener screws.
In conclusion, though seemingly small, fasteners and screws hold immense importance. Comprehensive consideration of various factors during selection and use is imperative to ensure robust and reliable connections.
