Poly Capped Elevator Bolts

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:

• Wear Out Quickly – PVC can’t withstand abrasion. In contrast, UHMW has up to 10× more wear resistance and maintains performance even after 250× more material loss.
   
• Easily Fall Off – Heat, vibration, or impact can loosen vinyl caps, exposing metal that could cause product damage or contamination.
   
• Don’t Seal Fully – Vinyl covers aren’t flush. Gaps allow dirt, moisture, and product infiltration—leading to bacterial buildup or liner damage.

Snap-on caps (commonly LDPE or polypropylene) may look clean, but they bring serious risks:

• Prone to Detachment – Internal clips can't match the secure hold of a molded bolt. They’re no match for vibration or impact.
   
• Lower Durability – LDPE and PP wear out quickly and can become brittle, especially in cold or high-impact environments.
   
• Not Designed for Industry – Many are generic and non-FDA-compliant, with dome shapes that catch debris and don’t provide a flush fit.

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. 

• Permanent Bond –  The UHMW head is molded directly onto the bolt with at least 1/4″ thickness, creating a rugged, vibration-proof seal. 

• Unmatched Durability – UHMW-PE has up to 250× the wear resistance of HDPE. It won’t crack, chip, or degrade—even under constant friction or sub-zero temps. 

• Flush, Sealed Surface – Counterbored installation creates a 100% poly surface, eliminating snag points and material infiltration. 

• FDA-Compliant & Safe – Our caps use food-safe, chemically inert polymers—perfect for hygienic environments and caustic wash-downs. 

• Faster Installations – No need for weld washers or extra plugs. These bolts streamline your assembly process while protecting your liners.
