Product Description

The bolt adopts an integrated structure comprising a hexagonal head, a flange, and a threaded shank, with the flange diameter enlarged by 30%–50% compared to conventional bolts. The patented technology disclosed in 2024 reveals an innovative design featuring a square-step shoulder with annular grooves, into which silicone rubber elastic sealing skirts are embedded. Adjacent skirts form a 0.3 mm oil-guiding channel, while a self-sealing oil injection port is integrated at the top. The shank employs a stepped design, consisting of a smooth cylindrical segment (accounting for 35%–45% of the length) and a threaded segment, with a 15° conical smooth neck section at the transition to enhance shear resistance.

Material Specifications
Aluminum Excellent thermal/electrical conductivity but naturally soft. May produce gelatinous buildup during processing.
Titanium EDM machining recommended. Requires deionized water to control heat during processing.
Steel Very strong metal. Wire cutting machines often preferred for complex features. Requires heat management.
Brass High tensile strength, easy to machine but requires slow cutting speed due to softness.
