Sleeve Anchor with Hex Flange Nut (Flange Head) – Yellow Zinc Anti-Vibration Masonry Bolt

The Sleeve Anchor with Hex Flange Nut (commonly referred to as a “Flange Sleeve Anchor” or “Serrated Nut Anchor”) is an upgraded masonry fastener designed for speed and security. Unlike standard anchors that require a separate washer, the Sleeve Anchor with Hex Flange Nut features an integrated wide-base nut. This design not only eliminates the risk of losing washers during high-altitude installation but also provides superior load distribution and vibration resistance.

Product Overview: Manufactured from Carbon Steel with a durable Yellow Zinc Plating, this heavy-duty anchor is ideal for fastening metal brackets, gate tracks, and machinery to concrete. The flange nut often includes a serrated bearing face, which bites into the fixture surface to act as a mechanical lock against loosening.

Engineering Insight: Why use a Flange Nut?

The Sleeve Anchor with Hex Flange Nut solves two common job-site problems:

• The “Missing Washer” Issue: When installing standard anchors overhead, washers often fall off and get lost. The flange nut is one solid piece, making installation faster and less frustrating.
• Load Distribution: The wide flange covers oversized holes in the fixture plate. Standard nuts might pull through a large hole, but the flange spans the gap securely, providing a stronger hold on thin metal channels or brackets.

For more details on nut types, please refer to the Flange nut entry on Wikipedia.

Installation Guide

1. Drill: Drill a hole of the same diameter as the anchor sleeve (e.g., 10mm bit for M8 anchor).
2. Clean: Remove dust to ensure maximum grip.
3. Insert: Hammer the Sleeve Anchor with Hex Flange Nut through the fixture until the flange rests against the surface.
4. Tighten: Tighten the flange nut. The integrated washer face will clamp down firmly while the bottom cone expands the sleeve.
