Abstract
The utility model discloses a half-thread bolt. The half-thread bolt comprises a first hexagonal outer head portion (1), a polish rod (2) and a threaded rod (3). The half-thread bolt is characterized in that a second hexagonal outer head portion (4) is arranged at the outer end of the first hexagonal outer head portion (1), the outer diameter of the second hexagonal outer head portion (4) is smaller than that of the first hexagonal outer head portion (1), and the head portion of the first hexagonal outer head portion (1) and the head portion of the second hexagonal outer head portion (4) are respectively provided with a radial through hole (5). The half-thread bolt is good in applicability to a wrench.
Description
Technical field
The utility model relates to fastening piece, specifically is a kind of partial thread bolt.
Background technique
Present a kind of partial thread bolt comprises bolt head, polished rod and screw rod, the bolt of this routine is actual to exist following shortcoming when using: only be suitable for a kind of specification spanner because the outer-hexagonal size of bolt head is general, when turning, can only adopt a kind of spanner of specification, poor for applicability.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of spanner applicability good partial thread bolt.
The technical solution of the utility model is, a kind of partial thread bolt with following structure is provided, and comprises the first outer-hexagonal head, polished rod and screw rod; The outer end of the described first outer-hexagonal head also is provided with the second outer-hexagonal head, and the second outer-hexagonal head outer diameter is less than the first outer-hexagonal head, and the head of the described first outer-hexagonal head and the second outer-hexagonal head is provided with radial direction through hole.
The described second outer-hexagonal head pastes mutually with the first outer-hexagonal head.
The center of the center of the described first outer-hexagonal head and the second outer-hexagonal head is on same straight line.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the outer end of the described first outer-hexagonal head also is provided with the second outer-hexagonal head, and the second outer-hexagonal head outer diameter is less than the first outer-hexagonal head, when pulling, be suitable for the spanner of two kinds of specifications, applicability is good.Because the head of the described first outer-hexagonal head and the second outer-hexagonal head is provided with radial direction through hole, and the strip instrument can pass radial direction through hole wrenching bolt again, applicability is good again.
