Key Features & Benefits:

• One-piece, burr-free construction: Provides maximum electrical conductivity.
• Electrical bright-tin plating: Offers maximum corrosion resistance.
• Annealing: Relieves stress points and assures maximum installed strength.
• Barrel-to-pad transition design: Minimizes flexing and bending.
• Open-end design: Permits visual inspection of wire location before and after crimping.
• Multiple V grooves: Provide maximum hold on wire for excellent holding power.
• Injection molded insulations: High quality, 221F (105C) rated, tough, resistant electrical grade materials.
• Funnel barrel construction: Ensures positive, easy wire insertion without strand hang-ups.
• Crimp ridge: Designed for positive tool location, resulting in fewer miscrimps.
• Non-slip ridge: Aids in tool positioning for proper crimping.
• Beveled leading edge: Facilitates easy wire insulation entry.
• Insulation grip (on select models): Provides a second crimp on wire insulation for additional strain relief, excellent for high vibration applications.

• Insulated 3M terminals withstand temperatures up to 221F (105C).
• High Temperature Terminals and Connectors: Rated for continuous use at 900F (482C).

Technical Specifications (Examples):

Note: Detailed specifications for each product type (Ring Tongues, Forks, Disconnects, etc.) are extensive and provided in the original document. Below are examples of the types of data available.

Tools:

• TH-440: Compact, high-quality tool for 2210 AWG terminals. Features include anvil-type wire cutter, crimp dies for insulated/non-insulated terminals, cut-off dies for screws, and wire stripping stations.
• TH-450: Versatile, heavy-duty tool for 266 AWG terminals. Features include anvil-type wire cutter, multiple crimp dies for insulated/non-insulated terminals, cut-off dies for screws, wire stripping stations, and strip length guide.
• TR-482: Ratchet tool for simultaneous crimping of barrel and insulation grip on 2210 AWG insulated terminals. Features color-coded dies, field re-calibration, terminal locator, conductor stop, and positive closure.
• TR-490: Ratchet tool for independent crimping of barrel and insulation grip on 2210 AWG insulated and non-insulated terminals. Features color-coded dies for insulated and non-insulated applications, field re-calibration, and positive closure.

Kits:

• STK-1 (Scotchlok Terminal Kit): Filled with popular low voltage termination products, including terminals and tools. Housed in a durable metal box with organized compartments.
• Scotchlok Steel Terminal Box (Empty): Metal case with plastic insert tray for organizing terminals.
• Scotchlok Plastic Terminal Box (Empty): Plastic organizing box for terminals.

Glossary of Terms:

• Adapters: To interconnect two connectors already attached to wires.
• Block Fork: Same strength as a fork, but designed for terminal blocks with flat sides against the barrier.
• Butt Connector: Uses chamfered barrel ends for fast wire insertion from both ends and a built-in wire stop. Must be crimped at both ends.
• Closed-End Connector: Used for pigtailing two or more wires.
• Fork: Allows rapid connection of wire, typically used on free-standing studs.
• Locking Fork: Spring-like tongue locks onto the stud, even if the mounting screw is loose.
• Parallel Connector: Similar to butt connectors but with overlapped wires and a single crimp in the center.
• Pin Terminal: For installation in compression blocks, commonly used in Europe for terminating stranded wire.
• Quick Connect (Disconnect): Attached by the female part's tongue slipping over the male tab, allowing easy and quick disconnection.
• Ring Tongue: Standard tongue style, offering the safest and most reliable connection.
• Tab: Uses a mounting hole for a rivet or screw.
• Tap: Requires no wire stripping; wire is laid in the connector and crimped.
