一、Keysert插銷螺套 73057簡介
Keyserts are solid，one-piece，key-locking inserts used to repair damaged threads or for use in original equipment。
Keysert是一種堅固的一體式鍵鎖螺套，常用來修復(fù)損壞的螺紋或者在一些設(shè)備中作為初始裝備使用。
The Keysert locking keys provide a positive mechanical lock which prevents rotation due to vibration or torsion。
Keysert的插銷鍵可以提供一個強(qiáng)力的機(jī)械鎖以阻止工件因振動或扭力而發(fā)生旋轉(zhuǎn)。
Keyserts are available in carbon or stainless steel，both in inch and metric series。
Keysert產(chǎn)品材質(zhì)上分碳鋼和不銹鋼兩種，規(guī)格上同時具備英制和公制尺寸系列。
Thinwall，Heavy Duty，Extra Heavy Duty，and Solid insert styles are available separately or in kits containing a range of sizes。
Keysert有薄壁型，重型，特重型，實心型等幾種，各自都有一個系列規(guī)格。
Installation tools are also available separately or in a range kit。
安裝工具可單獨購買或作為工具包整體購買。

五、Installation and Removal安裝和拆卸
Installation安裝
1、Drill out old threads with a standard drill。用標(biāo)準(zhǔn)鉆頭進(jìn)行鉆孔，注意適當(dāng)?shù)菇?(82°-100°)。
2、Tap new threads with a standard tap用標(biāo)準(zhǔn)絲錐進(jìn)行攻絲
3、.Screw in the insert until slightly below surface。將螺套裝進(jìn)去至稍低于工件表面。
4、Drive keys down with several hammer taps on the proper installation tool。用適當(dāng)?shù)墓ぞ邔⒉邃N鍵敲入插銷螺套里。
Removal拆卸
1、Drill out material between keys and internal thread with standard drill to specified depth (refer to charts for proper dimensions)。將螺套鉆掉一部分到一定的深度。
