Poly Capped Bolts are steel fasteners permanently molded with ultra-durable UHMW polyethylene caps. Unlike vinyl or snap-on covers, these caps don’t loosen, degrade, or allow contamination — making them ideal for agriculture, food processing, and high-impact environments.
Poly Capped Bolts are made by compression molding Ultra High Molecular Weight Polyethylene (UHMW-PE) plastic directly to the elevator bolt. The entire head of the bolt is covered with UHMW with a minimum of 1/4″ seal. This process greatly reduces the possibility of the UHMW poly capped bolts heads becoming detached.
Our poly capped elevator bolts can be used in a variety of applications where there is excessive friction and wear or high velocity. They excel at protecting steel, aluminum and wood surfaces. Our UHMW Poly Capped Bolts are used by companies with products that require a 100% UHMW poly surface, even where hardware needs to be attached to the existing poly surface.
Our Poly Capped Bolts offer customers the ability to securely fasten parts together and maintain a 100% poly on poly surface. For material handling and conveyance applications, this improves performance by reducing drag and increasing the longevity of material handling and conveyance system parts. Our purpose-built counterbore tools allow customers to easily make the perfect hole for the UHMW capped bolt every time, leaving the head of the Poly Capped Bolt flush with the plastic sheet material.
When it comes to high-wear, high-impact environments like agriculture, material handling, food processing, and industrial machinery, not all fasteners are created equal. Pride Solutions’ UHMW Poly Capped Bolts are specifically engineered to outperform vinyl bolt caps and snap-on bolt covers in every critical category.
Vinyl (PVC) bolt caps may offer quick cosmetic coverage, but they’re not built for industrial demands. These friction-fit caps:
UHMW has up to 10x more wear resistance than PVC.
Snap-on caps (commonly LDPE or polypropylene) may look clean, but they bring serious risks:
Pride Solutions’ Poly Capped Bolts are compression molded with Ultra High Molecular Weight Polyethylene (UHMW-PE) — a one-piece fastener built for long-term industrial reliability.
Pride Solutions’ Poly Capped Bolts are the industry’s most reliable choice for wear-resistant fasteners, food-safe bolt heads, and flush poly bolt installations. Upgrade your fastening system and extend the life of your equipment — safely and efficiently.

A Poly Capped Bolt is a specialized fastener where a UHMW (Ultra High Molecular Weight) polyethylene cap is compression molded directly onto the bolt head. This creates a one-piece, high-durability bolt designed to provide a 100% flush, wear-resistant poly surface—ideal for applications involving liners, augers, chutes, and conveyors.
Unlike vinyl bolt covers or snap-on caps, Pride Solutions’ Poly Capped Bolts are compression molded—not just attached. This means the UHMW cap is permanently bonded to the bolt head, forming a rugged, seamless unit. They are engineered to withstand abrasion, impact, vibration, and chemical wash-downs, making them ideal for food processing, agriculture, and industrial equipment.
Snap-on bolt caps typically use low-friction clips or ridges to attach to bolt heads. These caps are often made from LDPE or polypropylene, which lack the mechanical grip and durability needed for high-vibration or high-impact environments. As a result, snap-on caps can easily detach from bolts during operation—exposing sharp metal heads that can damage equipment, contaminate product, or cause safety issues.
A wear resistant elevator bolt cap, like those on Pride Solutions' bolts, dramatically extends the service life of conveyor and auger systems. The UHMW material resists friction, won’t crack or chip under impact, and prevents metal-on-poly wear. This reduces downtime, eliminates frequent bolt replacements, and protects both liners and product flow.
Yes. Pride Solutions uses FDA-compliant UHMW-PE, which is chemically inert and suitable for use in food and pharmaceutical processing. Unlike vinyl caps, which may contain non-food-safe additives, our Poly Capped Bolts are designed for hygienic environments where contamination and corrosion are major concerns.
Yes. In fact, they’re designed for it. Using our optional counterboring tools, the bolts can be installed flush with liner surfaces—creating a smooth poly-on-poly finish that eliminates snag points, protects product flow, and enhances safety.
