IMSCREWS 1/4"-20 x 7/8" 304 Stainless Steel Carriage Bolts (25 PCS)

Reliable Fastening for Compact Structural Connections
The IMSCREWS 1/4" x 7/8" carriage bolt is designed for projects requiring reliable fastening in a specialized short size. With a standard 1/4-inch diameter, these bolts are well-suited for light-load joints where space is limited, such as assembling greenhouse frames, furniture, or joining thin timber sections. Built for stability, they offer the durability necessary for long-term use in outdoor and indoor applications.

High Durability and Safety-Focused Design
Forged from 18-8 (304) stainless steel, these fasteners are highly resistant to corrosion in humid environments and are compatible with various materials. The smooth round head offers a clean appearance that reduces snagging hazards, making them an ideal choice for railings, play sets, and benches. The integrated square neck prevents the bolt from spinning, allowing for easy, one-sided installation with a single wrench.
