Description

Safety Wire Nut and Imperial/Metric Bolt Drill Jig Kit – 3-Piece Set

Brief Overview

This is a precision drilling jig system designed specifically for drilling safety wire holes through bolt heads and nuts with consistent accuracy. The kit eliminates guesswork and hand-drilling errors by providing indexed, threaded holes for both imperial and metric fastener sizes. Whether your customers work on aircraft maintenance, motorcycle restoration, or industrial assembly, this kit ensures diagonal safety wire holes are drilled cleanly and at the correct angle every time.

If your customer base requires fastener-specific solutions, you may also stock the metric-only bolt drill jig or imperial-only bolt drill jig for customers with standardized fastener specifications.

Key Features

  • Three-piece composition: Two metal drill guide bars (one imperial-calibrated, one metric-calibrated) plus one adjustable black cast clamp
  • Imperial sizing: Includes threaded holes for standard imperial bolt sizes (5/16", 1/4", and others as engraved)
  • Metric sizing: Includes threaded holes for metric bolt sizes (M8×1.25, M10×1.25, and others as engraved)
  • Accommodates bolts and nuts up to 3.5mm diagonal through the fastener head or nut face
  • Diagonal drilling capability: Clamp assembly secures fasteners at the correct angle for safety wire passage
  • Machined metal construction: Nickel-plated or polished steel bars with tapped internal threads; black oxide cast clamp
  • Engraved size markings: Clear imperial and metric size annotations on bar tops for quick fastener identification
  • Captive clamp screw: Integrated threading mechanism prevents loss during field use

Business Advantages

For Automotive and Motorcycle Dealers:

  • High-demand product for restoration shops and custom builders who regularly perform safety wire installation
  • Compact, retail-ready packaging (blister card with hang hole) supports impulse and planned purchases
  • Differentiate your parts offering from competitors by stocking precision tooling, not just consumables
  • Three-piece kit addresses both imperial and metric applications, reducing customer confusion about fastener standards

For Distributor Margins:

  • Specialized tool category with consistent turnover in the motorcycle and aerospace maintenance segments
  • Compact size enables high-density bin storage and efficient inventory management
  • Cross-sell opportunity: pair with safety wire itself, fastener kits, or specialty wrenches

Why This Kit Matters

Hand-drilling safety wire holes without a guide frequently results in:

  • Oversized or misaligned holes that weaken fastener security
  • Damaged bolt heads or nuts from slip-prone drilling
  • Inconsistent hole angles that complicate wire installation

This jig eliminates those risks by providing indexed, pre-threaded holes sized for each fastener specification. The diagonal clamp ensures the fastener sits at the exact angle required for safety wire passage. For shops that perform repeated safety wire installations—whether in motorcycle assembly, aircraft maintenance, or industrial equipment overhaul—this kit becomes an essential bench tool.

Call to Action

Stock this three-piece kit as your foundation for safety wire hole drilling. Pair it with complementary metric-specific or imperial-specific jig options for customers with dedicated fastener ecosystems, and watch your tooling section become the go-to resource for precision fastening solutions.
