Our premium external expansion bolts, available in 304 and 316 stainless steel, are engineered for heavy-duty fixing and mounting across indoor, outdoor, and harsh environments. Featuring a small head design, these pull burst and extension bolts come in M8, M10, and M12 sizes, delivering reliable, long-lasting performance for construction, home improvement, industrial, and coastal applications.
Crafted from high-grade 304 and 316 stainless steel, these bolts offer exceptional corrosion resistance and rust prevention. 304 stainless steel is perfect for general indoor/outdoor use, while 316 stainless steel provides enhanced durability in coastal, humid, or chemical-exposed areas—ensuring no rust, deformation, or breakage even with long-term use.
The external expansion design enables easy installation on concrete, brick, stone, and other hard surfaces: drill a matching hole, insert the bolt, and tighten to expand the sleeve, creating a firm, anti-slip connection with strong load-bearing capacity. The small head design ensures a low-profile, neat finish, ideal for tight spaces or scenarios where aesthetics matter, such as furniture mounting or fencing installation.
Widely applicable to wall mounting, concrete fixing, outdoor fencing, balcony railings, furniture installation, industrial equipment mounting, and coastal construction. Each bolt undergoes strict quality control, with precise dimensions, smooth threads, and a sturdy structure, ensuring easy installation and stable fixation even under heavy loads.
Whether for professional construction projects, home renovation, or outdoor equipment installation, these 304/316 stainless steel expansion bolts offer a durable, corrosion-resistant solution that meets all heavy-duty fixing needs.
