E-z Lok 650-14 Thread Locking Insert M14 X 2 Standard Wall

Product Description

The E-Z LOK 650-14 is a standard wall thread locking insert made from C12L14 carbon steel. It accepts an M14 x 2.00 internal thread and installs into a 7/8-9 tapped hole using a standard tap. Overall length is 11/16 inches (0.687 inches decimal). The smooth, rolled finish external thread locks the insert into the parent material, providing a durable threaded anchor point in softer or damaged base materials. This insert is suited for applications requiring Metric Coarse or Metric Fine thread compatibility in a single installed fastener solution. Machinists, millwrights, and maintenance technicians are the primary installers.

Thread locking inserts like the 650-14 are used in industrial, OEM, and MRO applications where a strong internal thread must be established or restored in metal, cast, or composite parent materials. The standard wall design fits conventional installation envelopes without requiring oversized bores. This insert is appropriate for both original equipment manufacturing and field repair scenarios where M14 x 2 thread engagement is required and the existing or prepared hole accepts a 7/8-9 tap.

Key Features

• M14 x 2.00 internal thread - compatible with Metric Coarse and Metric Fine standards
• 7/8-9 external thread for installation into a standard-tapped host hole
• C12L14 carbon steel construction for strength and machinability
• Standard wall design suits conventional bore envelopes
• Smooth, rolled external thread finish locks securely into parent material

Compatibility

Designed for installation into parent materials tapped to 7/8-9 using a standard tap. Accepts M14 x 2.00 fasteners meeting Metric Coarse or Metric Fine thread standards. Suitable for use wherever an M14 x 2 threaded insert of standard wall design is specified.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using standard hand or machine tapping equipment. Prepare the host hole with a 7/8-9 standard tap before driving the insert. Power down or de-energize any associated equipment before beginning thread repair work in an assembled system. Do not exceed the torque capacity of the parent material, and verify thread engagement depth meets the requirements of the fastener application.
