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

Upgrade your masonry installations with the Hillman 1/4 in. diameter, 1-3/8 in. long steel hex head sleeve anchors — a reliable, ready-to-use solution for brick, concrete, and hollow block. This 50-piece boxed set ships with everything you need to secure a wide range of fixtures quickly and confidently.

Key advantages at a glance

  • Solid steel construction for durable, long-lasting performance in masonry substrates.
  • Hex head design provides easy driver access and a clean, flush final appearance.
  • Integrated screw included (screw length 1-3/8 in) for a complete, ready-to-use kit.
  • Precise sizing engineered for a 1/4 in drill hole with a minimum embedment of 1-1/8 in, ensuring reliable grip even in challenging materials.
  • Versatile in masonry ideal for mounting brackets, fixtures, and hardware to brick, concrete, or hollow block.
  • Bulk value 50 anchors per box, boxed for organized storage and quick replenishment on the job.

what makes this sleeve anchor kit stand out

Unlike loose fasteners, Hillman sleeve anchors are designed to expand securely behind the masonry once the screw is tightened, creating a strong, vibration-resistant hold. The combination of steel construction and the hex drive minimizes installation effort while maximizing pull-out resistance in common masonry substrates. The 1/4 in. diameter and 1-3/8 in. length strike a practical balance between compact fixtures and substantial load capacity, making this set ideal for light-to-medium mounting tasks.

Applications and use cases

  • Mounting electrical panels, distribution boxes, or wall outlets to exterior brick or interior concrete surfaces.
  • Attaching shelving brackets, light fixtures, or curtain rods to masonry walls.
  • Securing mailboxes, signs, or safety rails where a dependable anchor is essential.
  • Reinforcing hardware on hollow block walls where consistent embedment improves load performance.

installation tips for best results

  • Drill a clean 1/4 in. hole to accommodate the sleeve anchor.
  • Insert the anchor through the fixture and into the hole, then tighten the screw to achieve the recommended minimum embedment of 1-1/8 in.
  • Avoid over-tightening, which can over-expand the sleeve and reduce grip in softer masonry.
  • Ensure the substrate is free of dust and debris for a solid initial bite and consistent performance across all 50 anchors.

Why choose Hillman sleeve anchors? This kit combines dependable strength with practical design details, like a hex head that’s comfortable for standard drivers and a pre-matched screw length that streamlines installation. The result is a fast, secure anchoring solution you can trust for everyday masonry projects—whether you’re remodeling, repairing, or undertaking a small construction upgrade.

Package contains 50 sleeves with screws, all from the Hillman brand, designed for use in brick, concrete, and hollow block. For consistent performance across projects, store the boxed set in a dry place and replace any damaged anchors promptly to maintain reliable holds on future installations.
