钢丝螺套是一种新型的螺纹紧固件，装入产品后能符合国际标准高精度内螺纹，其性能优于直接攻丝形成的螺纹。
螺纹护套按尺寸分类为：公制和美制。
螺纹护套按镀层分类为：无镀层，干性润滑剂涂层（二硫化钼），镀镉，Primer Free TM，镀银。
钢丝螺套按照螺距分：粗牙和细牙
粗牙钢丝螺套螺距一般为标准规格，常用的粗牙钢丝螺套规格如下：

使用方法主要包括以下四个环节：
1 钻孔
使用标准钻头钻孔，钻孔深度大于或等于钢丝螺套安装深度；注意不要将孔钻成锥形，切屑不要掉入。钻孔后锪孔不应超过0.4 螺距深度，因为锪孔过大不利于钢丝螺套的旋入。
螺纹规格 | 钻头直径（ mm) | 螺纹规格 | 钻头直径（ mm) |
M2x0.4 | 2.1 | M8x1 | 8.3 |
M2.5x0.45 | 2.6 | M10x1 | 10.3 |
M3x0.5 | 3.1 | M10x1.25 | 10.3 |

M18x2.5 | 18.6 | M22x2 | 22.5 |
M20x2.5 | 20.6 | M22x1.5 | 22.4 |
2 攻丝
使用标有规定螺纹规格的钢丝螺套专用丝锥攻丝，攻丝的长度必须超过钢丝螺套长度，对于通孔，要全部攻丝；攻丝的精度决定终标准内螺孔的公差带，使用者要适当地选择攻丝方法和润滑，盲孔攻丝要适当用力， 以防折断丝锥。攻丝后，螺纹孔应清理，一般用压缩空气喷枪吹，盲孔时还应使用带径向孔的长喷枪自下而上清理， 也可以用清洗的方法清理螺纹孔。螺纹孔精度高时，应用专用钢丝螺套底孔塞规进行检查。
3 安装
在一般情况下应用手工安装器进行钢丝螺套安装。钢丝螺套放入装工具内，使安装柄嵌入导杆槽内转动安装工具手柄使钢丝螺套旋入螺孔，并使其距表面有0.25-0.75 圈空螺纹。少量安装钢丝螺套时和M14×2 以上粗牙钢丝螺套安装时可采用“T ”型开槽或螺纹头简易工具安装，并注意不要在钢丝螺套安装柄上施加较大的轴向力以防‘乱扣’ 。钢丝螺套安装后，为检查所形成的标准内螺纹孔精度等级，可用相应的级别塞规检验。
4 去柄
对有折断槽的钢丝螺套，旋入螺孔后应将安装柄去除，需用去柄工具。通孔时，要将钢丝螺套安装柄折断，一般用冲断器对准安装柄，用 200g 左右的榔头猛打一下即可去除，对于 M18×2.5 以上的粗牙钢丝螺套和 M14×1.25 以上的细牙钢丝螺套 , 用尖嘴钳上下弯曲安装柄就能折断，然后将断下来的安装柄从螺孔中取出即可。
一、钢丝螺套专用丝锥
钢丝螺套专用丝锥用于加工钢丝螺套安装孔的专用内螺纹，结构尺寸依照国家标准《细柄机用和手用丝锥》GB3464－83要求制造，材料为W18Cr4V，可机用也可手用，根据其使用范围可分为轻合金机用螺纹护套丝锥、手用螺纹护套丝锥，普通钢机用螺套丝锥、手用螺套丝锥，特种螺套丝锥三种。
1、轻合金机、手螺纹护套丝锥
用于加工铝、镁合金以及铜合金等有色金属合金，螺距在2.5mm以下为单支丝锥，螺距大于等于2.5mm为双支。
标记示例：STd × p ST 为螺纹护套专用内螺纹代号
用于在轻合金上加工安装规格为8×1.25钢丝螺套底孔螺纹的专用丝锥，标记为：ST8×1.25（ST为钢丝螺套专用内螺纹代号）。
2、普通钢机、手用螺纹护套丝锥
用于加工钢、铸铁、铸钢等金属材料上的内螺纹，是双支丝锥。
3、特种丝锥
可根据用户需要设计、制造各种特殊品种的螺纹底孔丝锥，例如在软铝，紫铜上攻丝的机用、手用挤压丝锥，单支普通钢攻丝的专用机用丝锥、不锈钢攻丝丝锥、用于盲孔的平底丝锥、螺旋槽丝锥、螺尖丝锥等。钢丝螺套丝锥、螺纹护套丝锥的选择
◆直槽螺纹护套丝锥通用性很强，通孔或盲孔、有色金属或黑色金属都可使用，价格也便宜，但质量较差。螺纹护套直槽丝锥
◆螺旋槽螺纹护套丝锥比较适合加工盲孔螺纹，加工时切屑向后排出。在加工黑色金属时，螺旋角选择的少小一点，大约一般在 30 度左右，可以保证螺旋齿的强度。在加工有色金属时，螺旋角选择的少大一点，大约一般在 45 度左右，这样切削时可以锋利一些。
◆挤压丝锥比较适合加工有色金属，尤其是铝合金铸件，它主是对金属挤压、变形、形成的内螺纹。挤压成形是非切削加工，采用挤压成形工艺加工出的螺纹孔，抗拉、抗剪强度高，加工表面的粗糙度也较好，但挤压丝锥底孔要求较高，过大，强度不够；过小容易造成丝锥断裂。
◆ 螺尖丝锥比较适合加工通孔螺纹，加工时切削向前排出。固芯部尺寸较大，强度较好，切削力较大，所以对加工有色金属、不锈钢、黑色金属效果都很好。
二、钢丝螺套安装工具
钢丝螺套安装工具就是钢丝螺套安装扳手，也叫钢丝螺套旋入工具。
钢丝螺套安装扳手使用方法就是将钢丝螺套放入专用钢丝螺套安装工具内，使安装柄嵌入导杆槽内，转动钢丝螺套安装工具手柄使钢丝螺套旋入螺孔。其安装原理就是使钢丝螺套通过一段引导螺纹，迫使外径收缩，以便顺利装入底孔。安装时注意不可在钢丝螺套上施加较大的轴向力，以防"乱扣"。
钢丝螺套安装扳手分为分为手动及半自动两种。
● 手动钢丝螺套安装工具
手动钢丝螺套安装扳手，主要有套筒型安装扳手和简易钢丝螺套安装扳手两种。
（1）套筒型螺纹护套安装扳手
用于手动安装 ST2 × 0.4以上规格螺纹护套 标记方法： ST d × p
（2）简易螺纹护套安装扳手
简易螺纹护套安装工具有螺纹头、光杆两种。用于少量安装，一般维修、实验时用，操作时不易安装，钢丝螺套容易报废。
● 半自动安装扳手
半自动安装扳手有气动、电动两种，具有**、快速，安装定位准确的特点，用于批量钢丝螺套的安装或在装配生产线上使用。
三、钢丝螺套安装柄去除工具（冲断器）
冲断器主要作用就是用来折断钢丝螺套安装尾柄。
钢丝螺套在安装后，一般通孔都要求将尾柄去除掉，具体方法是用冲断器对准安装柄，用200g的榔头猛打一下，即可去除，对于18X2.5以上的粗牙丝套和14X1.25以上的细牙丝套，用尖嘴钳上下弯曲安装柄就能折断。
四、钢丝螺套取出工具---卸套器
钢丝螺套在安装过程中出现问题需要取出，应当使用专用钢丝螺套取出工具---卸套器，将卸套器放入钢丝螺套孔内，对准手柄用榔头猛击一下，用手加力按下手柄反螺纹旋转即可取出钢丝螺套。
五、钢丝螺套专用内螺纹塞规—底孔塞规
钢丝螺套装配的精度等级，取决于攻制的螺纹孔精度；在对钢丝螺套安装精度要求较高的情况下，可以在用钢丝螺套专用丝锥（ST丝锥）攻牙后，在钢丝螺套装配旋入螺孔之前，用钢丝螺套底孔塞规测量螺纹孔，对螺纹孔的精度进行检测，以此保证钢丝螺套安装后形成的内螺纹是标准的螺纹。
钢丝螺套底孔塞规也叫ST塞规，螺纹护套塞规，钢丝螺套塞规
钢丝螺套塞规用于检验钢丝螺套安装前的底孔尺寸，一般在对工作精度要求较高或用来鉴别丝锥是否磨损时使用，分为单头整体螺纹塞规及双头插柄底孔塞规，I级精度。
1、单头整体钢丝螺套塞规
用于检验ST2-ST5小规格钢丝螺套安装前内孔螺纹。
2、双头插柄钢丝螺套塞规
用于检验ST5以上规格钢丝螺套安装前内螺纹。
