What is a gland eye bolt?

A gland eye bolt is a bolt with a plain eye at one end and a thread at the other. The eye pivots on a pin and a nut on the thread clamps a component such as a valve or pump gland follower.

Is a gland eye bolt the same as a swing bolt?

Yes, the terms are often used for the same part: an eye-end bolt that swings on a pin. Naming varies by industry, so a drawing or sample is the best way to confirm the exact form.

How do I measure a gland eye bolt for replacement?

Record the eye bore, eye thickness, eye outside diameter, thread diameter and pitch, overall length and thread length. Note the pin diameter and lug gap on the equipment as well.

Why use stainless steel for gland eye bolts?

Glands sit close to process fluids, leaks and washdown. Stainless steel resists corrosion in these conditions, helping the bolt stay adjustable and removable during maintenance.

Can nuts and washers be supplied with the bolts?

Matching nuts and washers can be included. State the quantity of sets required with your enquiry.

Do you supply gland eye bolts to a drawing?

Yes. A dimensioned drawing is preferred; a sample or equipment reference can also start the technical review.

Quick answer

What is an SS gland eye bolt?

An SS gland eye bolt is a stainless-steel bolt with a plain eye at one end and a thread at the other. The eye pivots on a pin while a nut on the thread applies clamping force — a typical example is tightening the gland follower on a valve or pump stuffing box.

Also known asStainless gland bolt · Swing bolt · Hinged eye bolt · Eye-end bolt

Key takeaways

The eye is pinned, allowing the bolt to swing into position.
Commonly used on gland followers, hinged covers and linkages.
Eye bore must match the pin diameter and lug width.
Stainless construction suits wet and process service.

How SS Gland Eye Bolts Work in Practice

Unlike a lifting eye bolt, a gland eye bolt is designed to pivot. The eye fits over a pin between lugs, so the bolt can swing out of the way for maintenance and swing back to clamp. A nut and washer on the threaded end then draw the mating part down.

This makes it a practical choice for valve and pump packing glands, inspection covers, hinged clamps and adjustable linkages. Accurate eye bore, eye thickness and thread length are essential for a correct fit with the existing assembly.

Common Gland Eye Bolt Forms

Plain eye swing bolt

Round eye with a bore for a pin; the most common gland and hinge form.

Forked or clevis end

An alternative end where the bolt straddles a single lug — confirm against your drawing.

Fully or partially threaded

Thread length is set by the clamping travel the gland or cover requires.

Supplied with nut & washer

Matching stainless nuts and washers can be included in the enquiry.

How to Choose the Right SS Gland Eye Bolt

Eye-to-Pin Fit

The eye bore and thickness must match the pin and lug gap so the bolt pivots freely without excess play.

Thread Travel

Thread length should allow full clamping and future adjustment as packing or seals compress.

Process Media

State the fluid, temperature and washdown conditions so the stainless grade can be reviewed.

Equipment Reference

A valve or pump model, drawing or sample bolt is the fastest route to an accurate replacement.
