Safety Pin Dimensions and Pack Size

The MIDWEST FASTENER 67104 safety pin measures 2-3/4 inches in length and comes in a four-piece pack. Zinc-plated steel construction provides corrosion resistance for automotive, agricultural and general hardware tasks. The square wire lock design secures connections in vibration-prone environments. Homeowners, mechanics and maintenance crews use these pins for quick, repeatable fastening.

Corrosion Resistance and Mechanical Reliability

Zinc plating protects the steel body from rust during outdoor or under-vehicle exposure. The square wire lock mechanism holds position without tools, reducing loosening from shock or thermal cycling. No moving parts generate noise and the pins draw zero power, making them silent and passive in any assembly. Installation and removal are manual operations with no energy cost.

Replaces Cotter Pins and Single-Use Fasteners

These lock pins replace disposable cotter pins, hairpin clips or hitch pins that deform on removal. The reusable design suits applications requiring frequent disassembly such as trailer couplers, implement pins or guard hinges. The jump is worthwhile when a joint is opened weekly or monthly and a tool-free, non-consumable fastener saves labour time. Buyers needing a permanent, tamper-resistant connection or a different diameter should select an alternative fastener type.

Questions about this item

How do I install the 67104 safety pin and what step is often missed?

Insert the 5/16 inch diameter pin through the aligned holes until the square wire loop snaps fully over the end; the step often missed is confirming the loop has locked completely.

What maintenance or replacement will the 67104 safety pin need later?

Inspect the zinc plated steel for corrosion or bending before each use; replace the pin if the wire loop loses tension or the shaft shows visible wear.

What limit appears first on the 67104 safety pin under sustained use?

The zinc plating wears first, exposing the steel to rust which weakens the 5/16 inch shaft before the square wire loop fails.
