WMP Safety Wire Nut And Imperial Bolt Drill Jig Kit

• Two-piece kit: separate nut drill jig and bolt drill jig
• Nut jig accepts nuts up to 1-3/8" diameter
• Bolt jig covers six imperial sizes: 1/4"-20, 5/16"-24, 5/16"-18, 3/8"-16, 3/8"-24 and 7/16"-14
• Guides the bit for a straight hole without slipping off the fastener
• Drills holes up to 2mm — requires a 2mm or smaller drill bit (not included)
• Allows critical nuts and bolts to be safety wired against vibration loosening
• Suits scrutineering and race preparation as well as general workshop use
• Works with WMP safety wire (HWSSW0705KG, HWSSW0710M, HWSSW12) and safety wire pliers (TMPSWS, TMPSWL)

• Nut drill jig
• Imperial bolt drill jig

Match the jig to the fastener first — use the bolt jig hole that corresponds to the thread size, or the nut jig for nuts up to 1-3/8".
Secure the jig firmly on the fastener before drilling so the guide bushing sits square to the flat.
Use a 2mm or smaller drill bit; anything larger will not pass through the guide and can damage the jig.
Run the drill at a moderate speed with steady, light pressure rather than forcing it, and back the bit out periodically to clear swarf.
A drop of cutting oil on the bit helps with hardened fasteners and extends bit life.
Deburr the drilled hole and blow or brush the fastener clean before threading safety wire through it.
Clear metal filings from the guide holes after each job so the jig continues to seat flush.
Wipe the jigs clean and apply a light film of oil before storing to prevent surface rust.
Store the kit dry, and inspect the guide holes occasionally — a worn or bell-mouthed guide will no longer hold the bit straight.
Always wear eye protection when drilling, and clamp loose fasteners in a vice rather than holding them by hand.
