Rod Anchor Screw 50 Pcs 3/8 in Fitting 1/4 x 2 in Threaded Hanger

In this review the reviewer tested the Gisafai 50 piece rod anchor screw pack to see whether it delivers reliable anchoring for overhead timber and vertical concrete installations. The bottom line: this pack is aimed at contractors and DIYers who need a bulk, ready-to-install threaded rod hanger that resists corrosion and handles high stress without pre-drilling in many common construction substrates. The single biggest reason to buy is the combination of a hardened, zinc-coated screw and a 3/8 in rod fitting in a 50-piece quantity that reduces trips to the store and speeds repetitive installs.

Key Features

• Quantity and convenience: Fifty rod hanger anchors in one pack reduce downtime on larger projects and keep spares on hand.
• Durable material: Made of galvanized carbon steel so each anchor resists wear and corrosion in typical construction environments.
• Trusted screw construction: Case hardened and heat treated with a zinc coating to improve strength and corrosion resistance under load.
• Clear dimensions: Two inch screw length with 1/4 in screw diameter and a 3/8 in rod fitting for consistent, compatible attachments.
• Wide application: Designed for overhead timber and vertical concrete structures, and usable in wood, steel, drywall, purlins and metal decking.
• Fast install: Threaded design allows one- or two-step rod attachment that reduces installation time and lowers risk of over driving fasteners.

Who It's For

This product suits professional builders, HVAC and electrical contractors, and experienced DIYers who install threaded rod hangers repeatedly and need a reliable bulk supply. The pack works well where corrosion resistance and hardened screw performance matter, such as outdoor eaves, rafters, and industrial interiors.

It is less appropriate for decorative household uses that require specialized finishes or for projects where metric fasteners are required. Also, buyers who need custom-length screws or integrated anchors for hollow-wall applications should look elsewhere.

Pros & Cons

Pros
