Product Identity

MIDWEST FASTENER CORP 53199 lock pins are zinc plated steel fasteners designed for securing assemblies with a square wire locking mechanism. They suit maintenance technicians, fabricators and hobbyists who need reusable, corrosion resistant pins for alignment or retention tasks.

Practical Limits

The square wire lock design provides a positive mechanical hold that resists vibration but requires manual insertion and removal. Zinc plating offers moderate corrosion protection suitable for indoor or sheltered outdoor use, not continuous exposure to salt spray or harsh chemicals. Diameter and length are fixed, so the pin cannot adjust for variable grip ranges or oversized holes.

Deciding Specification

The 3/8 inch diameter by 2-1/2 inch length determines whether this pin matches the hole size and material thickness of your application. Verify both dimensions against your drawings before ordering, as no other size or finish options are included under this part number.

Questions about this item

Does the 53199 come in other sizes or pack quantities?

The supplier data lists only the 3/8" x 2-1/2" zinc plated steel square wire lock pin under part number 53199; no alternate diameters, lengths or pack counts are shown.

What does the 3/8" x 2-1/2" dimension mean when the pin is installed?

The pin body measures 3/8 inch in diameter and 2-1/2 inches in overall length, so it fits a 3/8 inch hole and provides 2-1/2 inches of usable grip before the square wire lock engages.

How does the square wire lock mechanism secure the pin in use?

The square wire lock snaps over the pin end after insertion, creating a positive mechanical stop that resists vibration and prevents the pin from backing out of the hole.
