2 Options for Metal Fasteners 2 Options for Metal Fasteners

Metal fasteners are divided into 2 types: permanent fasteners, and non-permanent fasteners.

1 - Permanent fasteners

These fasteners are typically attached with an adhesive, welding or soldering. Other types of permanent fasteners include: bolts, rivets, screws, clamps and retaining rings.

2 - Non-Permanent Fasteners

This type of fastener is used to attain a more temporary bond. These fasteners include: couplers and clamps that can be removed upon request. Usually non-permanent fasteners are attached mechanically. Choices of these types of fasteners often depend on the degree of fasteners strength required to hold 2 or more components together.

Metal fasteners are typically used in situations where greater holding strength is needed for heavier loads. Various types of materials can be used in certain types of metal fasteners to meet special needs. For example, titanium, can be used in situations where its greater strength meets a specific need.

Here are some advantages of both permanent and non-permanent metal fasteners:

Permanent:

  • Reduces damage to painted surfaces
  • Works better with surfaces that need to fit more closely
  • Eliminates corrosion usually associated with mechanical fasteners
  • Reduces panel "dimpling"
  • Fewer stress points from holes drilled to accommodate bolts and screws

Non-Permanent:

  • Connected materials can be shifted or changed
  • Worn or broken fasteners can be more easily replaced
  • Connections can be broken when needed
