Shook Manufactured Products 80021 Wood Anchoring System

Product Description

The SHOOK MANUFACTURED PRODUCTS 80021 is a wood anchoring system designed for vertical-mount applications in mechanical and construction trade work. The kit centers on a 5/16-inch x 2.25-inch hex head screw paired with a 3/8-inch, 16 TPI threaded rod, both constructed from steel for reliable load-bearing performance. The hex head drive style allows standard wrench or socket installation without specialized tooling. Each box contains 25 units, making it practical for multi-point installations on a single job. HVAC, plumbing, and electrical contractors use this type of anchoring hardware to secure equipment, pipe hangers, and support assemblies to wood framing and structural members.

This anchoring system is suited for residential and light commercial installations where threaded rod support assemblies must be anchored into wood substrates. Typical applications include securing threaded rod drop hangers for ductwork, conduit, pipe runs, and equipment supports in wood-framed construction. The vertical-mount orientation is standard for overhead support work in crawlspaces, basements, and attic spaces. Each box provides 25 complete anchor sets, which covers a typical run of support points on a single service call or installation phase.

Key Features

• 5/16-inch x 2.25-inch screw provides solid bite depth into wood framing members
• 3/8-inch diameter, 16 TPI threaded rod compatibility for standard hanger hardware
• Hex head drive style works with common wrenches and socket sets
• Steel construction provides strength suitable for mechanical support loads
• Vertical-mount design for overhead and drop-rod support installations
• 25 units per box for multi-point installation efficiency

Compatibility

Designed for use as a wood-substrate anchor for 3/8-inch threaded rod support systems commonly used in HVAC, plumbing, and electrical installations in wood-framed structures.

Installation Notes

Installation is performed by HVAC, plumbing, or electrical tradespeople during rough-in or equipment-setting phases. Confirm wood framing member integrity and locate fasteners into solid structural lumber, not sheathing or engineered panel edges. Use an appropriately sized hex wrench or socket to drive the screw to full seating without overdriving and splitting the substrate. Follow applicable building codes and manufacturer load ratings when determining anchor spacing for support rod systems.
