Shelf Support Grommets 5 mm & 1/4" Grommets - Pro Value Series BA1284BN

Shelf Support Grommets 5 mm & 1/4" For Clean Shelf Bores

Shelf Support Grommets 5 mm & 1/4" grommets from the Pro Value Series are nickel plated steel parts designed to size and finish 5 mm and 1/4 inch bore shelf pin holes, so cabinet shelf supports seat consistently in drilled panels. The nickel plated steel construction provides a hard metal bearing surface around each bore, which helps the shelf pin shoulder register against metal instead of raw wood. These grommets are sized to accept 5 mm and 1/4 inch bore shelf pins, so standard shelf supports can be used while the bore edges stay protected. Each grommet lines the hole to provide a finished appearance, which gives cabinet interiors and closet panels a more uniform, machined look around every adjustable shelf location. This design lets production shops and serious installers upgrade plain drilled holes to a more professional-looking, wear-resistant interface without changing shelf pin style.

Key Shelf Support Grommet Details For Projects

• The grommets are nickel plated steel, providing a rigid metal sleeve around the bore so shelf pins bear on metal instead of fiber, which supports repeated shelf adjustments in cabinet and closet applications.
• Grommets are sized to accept 5 mm and 1/4 inch bore shelf pins, so standard metric and fractional shelf supports fit the lined holes, allowing flexible hardware choices while keeping each bore protected.
• Each grommet lines the hole to provide a finished appearance, so exposed adjustable shelf rows in cabinets, closets, and garage storage show a continuous metal ring rather than raw drilled edges.
• The 5 mm grommet requires a 7/32 inch (5.3 mm) diameter hole, giving a clear drilling target that aligns metric shelf pins with a specific bit size for accurate, repeatable panel machining.
• The 1/4 inch grommet requires a 17/64 inch (6.7 mm) diameter hole, so installers can select a matching drill size that provides proper clearance for the grommet body and stable seating in the panel.

Hole Size And Depth Details For Straightforward Installation

The 5 mm bore grommet uses a 7/32 inch (5.3 mm) diameter hole and has a depth of 3/16 inch, so drilling to that diameter and depth produces a pocket where the grommet walls contact the panel and present a clean metal opening. The 1/4 inch bore grommet uses a 17/64 inch (6.7 mm) diameter hole and has a depth of 1/4 inch, which means a slightly larger and deeper cut is needed to seat the larger body flush while still centering the 1/4 inch shelf pin. Using the specified diameters and depths allows the nickel plated steel flanges to sit at the bore face while the barrel engages the surrounding material, supporting a snug, repeatable fit in production drilling or jig-based shop work.

Using Pro Value Series Grommets In Cabinet Work

Where These Nickel Grommets Are Typically Applied

These Pro Value Series grommets are in the shelf supports product class, so they are intended for use anywhere 5 mm or 1/4 inch bore shelf pins support adjustable shelving in cabinets, closets, or storage units. Because they are sized to accept 5 mm and 1/4 inch bore shelf pins, they can be matched to common metric pins in European-style cabinetry or 1/4 inch pins in many North American systems while still presenting the same nickel plated steel ring at the face. The way each grommet lines the hole to provide a finished appearance makes them suitable where the shelf pin rows sit at eye level, such as bookcases or open storage, since the visible bores show a continuous metal edge. In garage or workshop storage, the metal sleeve around the bore works with standard shelf pins to support frequent shelf height changes without the bore edges fraying as quickly as exposed wood.

Why The Specific Hole Diameters And Depths Matter

The 5 mm grommet requiring a 7/32 inch (5.3 mm) diameter hole gives a defined bit size that balances clearance for the grommet barrel with enough surrounding material to hold the nickel plated steel body, which supports consistent alignment across long rows of adjustable holes. Its 3/16 inch depth is shallow enough for typical cabinet side thickness while still providing a full metal liner where the 5 mm bore shelf pin passes, so the load transfers into metal at the contact area. The 1/4 inch grommet requiring a 17/64 inch (6.7 mm) diameter hole similarly defines the drilling step for panels that will carry 1/4 inch bore shelf pins, helping keep pin centers in line with design drawings. With a 1/4 inch bore grommet depth of 1/4 inch, the liner extends farther into the panel, which offers a deeper metal bearing surface around the pin shank and supports repeated shelf repositioning along heavier storage runs.

Common Questions About These Shelf Support Grommets

Selecting These Grommets For Precise Shelf Bores

Choose these Pro Value Series nickel plated steel grommets when 5 mm and 1/4 inch bore shelf pins are used and a finished bore edge is required, because they line the hole to provide a finished appearance and define hole sizes at 7/32 inch and 17/64 inch. The specified depths of 3/16 inch for the 5 mm bore and 1/4 inch for the 1/4 inch bore create a metal-lined channel that supports the shelf pin where it bears on the panel. For cabinet, closet, or storage work that relies on clean, repeatable adjustable shelf holes, these shelf supports help standardize drilling dimensions and present a consistent nickel ring at every bore.
