Value Collection 45220 M4x0.70 Threaded Insert 100-pack

Product Description

The VALUE COLLECTION 45220 is a knurled body open end threaded insert designed for creating strong, reliable threaded connections in thin materials, sheet metal assemblies, and plastic or composite panels. The insert features an M4x0.70 thread size and measures 6.73mm in insert diameter with an overall length of 10.67mm. Constructed from 1008/1010 steel with a clear protective zinc yellow dichromate finish, it provides corrosion resistance and mechanical durability in demanding fastening applications. The knurled exterior grips the host material when pressed or driven into the prepared hole, locking the insert in place without requiring adhesive. This insert is installed by electricians, millwrights, and assembly technicians working with light-gauge metal fabrication and enclosure work.

This threaded insert is suited for applications where a through-hole or blind-hole installation requires a permanent internal thread in material too thin to tap directly. Typical use cases include electrical enclosures, HVAC sheet metal panels, control cabinet assemblies, and light structural brackets. The open end design allows for bolt pass-through or stud engagement from either direction. A 6.75mm drill or punch is required to prepare the host material to the correct hole diameter before installation. Sold in a pack of 100, this insert is well suited for production runs and service stock.

Key Features

• M4x0.70 internal thread for standard metric fastener engagement
• Knurled exterior body locks securely into the host material without adhesive
• Open end design permits bolt pass-through from either side
• 1008/1010 steel construction with zinc yellow dichromate finish for corrosion protection
• Requires 6.75mm hole diameter for proper installation fit
• Sold in a pack of 100 — practical for production and maintenance stocking

Compatibility

Designed as an OEM-style replacement or production fastener for thin-material assemblies requiring a permanent M4x0.70 metric threaded insert, including sheet metal panels, enclosures, and composite substrates where direct tapping is not feasible.

Installation Notes

Installation is typically performed by sheet metal fabricators, electricians, or assembly technicians using a drill press or hand drill to prepare a 6.75mm hole prior to insert placement. Power down all electrical assemblies before working on panels or enclosures. Use the appropriate installation mandrel or press tool for the insert size to ensure the knurl seats fully and evenly into the host material. Do not attempt to install by striking the insert directly, as this can deform the internal thread.
