摘要： PURPOSE:To manufacture inexpensively a low strain screw by tightly holding a screw material with a clamping jig, hardening it at a specified temp., and tempering the hardened material as it is. CONSTITUTION:High-carbon alloy tool steel is worked into the shape of a screw by cutting or other method, and the screw material 1 is tightly held with a clamping jig 3 divided into an upper block 3b and an under block 3a. The material 1 is hardened at a slightly higher temp. than the temp. at which the martensitic transformation of the material 1 is started, and the hardened material is tempered as it is. The space S between both the blocks 3b, 3a is adjusted to about 1-2mm..
