Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Hillman 1/2 in. D x 2-3/4 in. L steel round-head strike anchors are built for dependable, long-lasting concrete mounting. This 25-pack boxed set gives you a sturdy, ready-to-use solution for securing fixtures directly to masonry, with a design that mixes solid steel construction and precise dimensions for consistent results across multiple projects.

Key advantages you’ll notice with these strike anchors:

  • 1/2" diameter steel round-head anchors provide a clean, compact anchor point with strong pull-out resistance in concrete.
  • Length of 2-3/4" and a minimum embedment of 2-1/2" ensure a deep, solid bite that stays secure under load.
  • Screw included (2-3/4" long) simplifies installation by pairing the anchor with a compatible fastener right out of the box.
  • Load capacity up to 400 (per anchor, when installed according to the instructions and on properly prepared concrete), making it suitable for a range of fixtures and supports.
  • Concrete-focused application—designed specifically to anchor hardware to masonry surfaces where a reliable, code-ready fastener is needed.
  • Boxed set of 25 provides ready access for multiple installations, field projects, or stocking a toolbox for ongoing use.

What you can mount with these Hillman strike anchors

  • Conduit hangers, brackets, and electrical fixtures to concrete walls or floors.
  • Light fixtures, ceiling mounts, and fan housings that require a robust masonry anchor.
  • Shelving supports, brackets, and hardware where a secure, clean finish is needed.

Installation at a glance

  1. Mark the drilling location and ensure the surface is clean and free of dust.
  2. Drill a 1/2" hole to a depth of at least 2-1/2" for proper embedment.
  3. Insert the strike anchor into the hole until the round head sits flush with the surface.
  4. Drive in the included screw to the specified depth, ensuring a tight, secure fit.
  5. Verify the mounted load remains within the 400 lb capacity per anchor and re-check after installation if mounting dynamic or heavy loads.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
