Stewart Fastener 6306 Drop-in Anchor 3/8 Inch

Product Description

The STEWART FASTENER 6306 is a 3/8 inch drop-in anchor designed for anchoring bolts and threaded rod into solid concrete. Drop-in anchors are internally threaded expansion anchors that are set by driving an expansion plug flush with the base material surface using a setting tool. Once set, the anchor accepts a standard threaded fastener to create a load-bearing connection. This type of anchor is widely used by contractors, electricians, plumbers, and mechanical trades when securing equipment, conduit hangers, pipe supports, or structural components to concrete.

The 6306 is suited for use in solid concrete applications in both residential and commercial construction. It is commonly installed in slabs, walls, and overhead concrete where a flush-mount, internally threaded anchor point is required. Trade professionals use this anchor when mounting mechanical equipment, electrical panels, conduit supports, and similar hardware to concrete substrates.

Key Features

• 3/8 inch internal thread size accepts standard 3/8 inch threaded fasteners and rod
• Drop-in expansion design seats flush with the concrete surface after setting
• Internally threaded body allows for clean, load-bearing fastener connections
• Suitable for a wide range of trade applications including mechanical, electrical, and plumbing rough-in work

Compatibility

Designed as a standard 3/8 inch drop-in anchor for use with 3/8 inch threaded bolts and rod in solid concrete base material.

Installation Notes

Installation requires drilling a properly sized hole in solid concrete and cleaning out debris before inserting the anchor. A manufacturer-specified setting tool is used to expand the anchor in place by driving the internal plug until flush. Licensed trade installers should follow applicable building codes and anchor manufacturer load tables when determining spacing and edge distance. Never install drop-in anchors in hollow, cracked, or deteriorated concrete.
