E-z Lok 901420-13 Flanged Hex Drive Insert 1/4-20

Product Description

The E-Z LOK 901420-13 is a flanged hex drive threaded insert designed to install strong, permanent 1/4-20 UNC internal threads into soft or low-density base materials. The flanged head seats flush against the material surface to resist pull-through under load. Drive installation is performed with an M6 hex key, making the installation process straightforward and repeatable. The insert measures 0.512 inches in overall length with an insert diameter of 0.469 inches, and it requires a 0.3543-inch hole diameter for proper seating. The minimum grip thickness supported is 0.5 inches. Made from zinc alloy, this insert balances corrosion resistance with ease of installation for indoor and light industrial applications.

Flanged hex drive inserts like the 901420-13 are used wherever a durable threaded connection is needed in a part that cannot support cut threads on its own. Typical applications include plastic housings, die-cast enclosures, and soft metal assemblies in manufacturing, electronics, and general fabrication environments. The 1/4-20 UNC thread pattern is one of the most common fastener standards in North American trade work, making this insert broadly applicable across production and repair scenarios. The package quantity is 100 pieces with a minimum order quantity of 1.

Key Features

• 1/4-20 UNC internal thread standard for broad fastener compatibility
• Flanged head design resists axial pull-through in soft base materials
• M6 hex drive installation requires no specialized tooling beyond a standard hex key
• Zinc alloy construction provides corrosion resistance in light-duty environments
• 0.512-inch overall length fits assemblies with a minimum grip of 0.5 inches
• 0.3543-inch required hole diameter works with a 23/64-inch drill bit

Compatibility

Designed for installation into soft materials requiring a permanent 1/4-20 UNC threaded insert with a flanged hex drive installation method. Consult the base material specifications to confirm the required hole diameter and grip thickness are met before installation.

Installation Notes

Installation is typically performed by machinists, assemblers, or maintenance technicians using a standard M6 hex key or driver bit. Drill the receiving hole to 0.3543 inches in diameter using a 23/64-inch bit before installing the insert. Ensure the base material meets the 0.5-inch minimum grip thickness to achieve full thread engagement. Power down and de-energize any assembly before installing inserts in or near electrical enclosures.
