Many construction and procurement companies often confuse car repair geckos with internally forced geckos. Although both belong to concrete anchor bolts, they have significant differences in stress principles, bearing capacity, and applicable working conditions. Choosing the wrong one can easily lead to safety hazards.
Car repair geckos belong to mechanical locking anchor bolts. Tightening the nut drives the wedge block to open the external clamp, and the clamp forms a bite lock with the concrete hole wall, not simply relying on friction. Advantages: High load-bearing capacity, shock resistance, impact resistance, immediate loading after installation, no need to wait for curing; Suitable for heavy-duty projects such as curtain walls, seismic supports, large equipment bases, and storage shelves.
The internal pressure gecko is an internal expansion anchor bolt. After being inserted into the borehole, the screw is screwed in to squeeze the internal cone plug, causing the casing to expand outward and be fixed by expansion friction. Advantages: Easy installation, suitable for blind holes; Suitable for medium load scenarios such as air duct ceilings, fire-fighting equipment, and lightweight brackets, it is not recommended for use in high vibration and heavy load areas.
Procurement suggestion: prioritize vehicle repair geckos for heavy-duty vibration engineering; Ceiling and lightweight fixation use internal pressure geckos. Hebei Jiaqi New Materials is equipped with a complete set of precision testing instruments, and all anchor bolt products have undergone pull-out testing with complete specifications.
