Our commitment to innovation and continuous improvement allows the FASTON quick connects to remain the leader in the industry. Recent extensions to the product line include an expanded range of low insertion force terminals, high temperature terminals, low profile terminals, and more.

Product Features

FASTON Terminals
  • Insulated and uninsulated
  • Straight and flag configurations
  • Stress relieved receptacles
  • Various plating options
  • Positive Lock connector solutions
  • High temperature solutions
  • Application tooling

FASTON terminals are available in brass and phosphor bronze which can be plated with tin or silver. The line also includes a selection of nickel plated steel tabs and receptacles. Certain products are available in either pre-tin or tin plated. Tin plate is the electro-depositing of tin on base metal over the entire surface of the terminal following the fabrication of the terminal. Pre-tin plate is the plating of tin on base metal prior to fabrication which produces exposed base metal in the terminal edge areas after stamping.


FASTON receptacles are available in both straight and flag configurations and come in a variety of sizes. These are designed numerically by a series number that corresponds to the width of the mating tab. Recent extensions to the product line include an expanded range of low insertion force terminals, high temperature terminals, and low profile terminals.


Precisely controlled crimping specifications for each FASTON terminal allow all connections to perform as specified. Low per line costs are derived from low initial product costs, high application speeds, and plug-in assemblies of the finished termination.


The process of stress relieving is unique to TE quick connects and is most commonly used in the production of those receptacles designated as premier line, including Ultra-Fast, Ultra-Fast Plus FASTON and PIDG receptacles. Stress is introduced into copper alloy or steel terminals during the stamping process. When metal strip is formed into the receptacle, the material is deformed beyond its yield stress to form it into its new shape. This forming operation leaves a residual stress in the grain structure.


The orientations and magnitudes of the forming stresses are complex, but can exist in the same direction as the applied load. Thus, residual stresses can reduce the force necessary to open the receptacle during the tab insertion. Stress relieving the terminal restores the elastic spring properties and improves receptacle performance by reducing the residual stresses. After stress relieving, the receptacle resists opening when a tab is inserted, especially where difficult or awkward mating situations may causemechanical abuse.

Product Line

Receptacles and Tabs
  • Flag Receptacles: Flag receptacles are a reliable termination for applications where space is a critical factor. These receptacles have a mating tab which is a right angle to axis of conductor. 
  • Straight Receptacles: Straight receptacles are created with or without insulation. Receptacles with insulation have diameters of .040-.230.
  • Wire Crimp Tabs: These tabs are specifically designed for line splices and other special applications. Wire Crimp Tabs can be applied to 22-14 AWG wire with "F" crimp termination and have insulation support.
  • Printed Circuit Board Tabs: Designed for PCB hole insertion and permanent fixing through solderling.
  • Board Mount Tabs: Available in all series. The mounting process for board tabs utilizes rivets or screws through stud holes. TE offers board mount tabs in 90 degree configurations and angled versions.
  • Locking Action and Contact Area: Designed to increase contact surfaces and lock tabs and receptacles at the proper insertion depth for firm retention.

Materials and Finishes

FASTON Terminals
  • Phosphor Bronze Plain: Used in applications where brass would normally corrode - such as ammonia.
  • Brass Plain: Used frequently where applications have optimal environmental conditions.

  • Steel Nickel Plated: Allows for reliable connections at high temperatures. Suitable for appliance applications.
  • Brass / Phosphor Bronze Silver Plated: Silver plated connections allow the highest operating temperature and higher current carrying capacity corroded. Suitable for ammonia.

  • Brass / Phosphor Bronze Tin Plated: Tin plating of receptacle and tab improves operation at higher temperatures, and in addition helps to protect the connection against corrision.

Forces for Crimp Pull-Out: Tensile Strength

Maximum tensile strength of the wire to terminal connection does not ensure reliable electrical performance. An acceptable compromise between maximum tensile strength and electrical stability is recommended. Normally, the tensile strength is much greater than the force required to disconnect the tab from the receptacle; therefore, no difficulties or hazards are encountered.


The forces shown for the crimp pull out test represent the minimum force required to seperate the wire from the crimped terminal in an axis parallel to the wire exit direction from the contact. This force does not include the holding force of the insulation crimp (if applicable).
