IMSCREWS 3/8"-16 x 3/4" Heavy-Duty 304 Stainless Steel Carriage Bolts (20 PCS)

Substantial Strength for Compact Structural Connections
The IMSCREWS 3/8" x 3/4" carriage bolt is engineered for projects requiring maximum shear resistance in a compact, low-profile size. With a robust 3/8-inch diameter and a 0.75-inch length, these bolts are well-suited for joints where stability is critical but clearance is limited, such as mounting heavy-duty metal brackets to thin wood panels or reinforcing structural frames. Built for durability, they offer the stability necessary for long-term use in residential DIY projects and industrial applications.

High Durability and Security-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners are highly resistant to rust and corrosion in coastal or humid environments. The smooth round head offers a clean, tamper-resistant appearance that reduces snagging hazards, making them an ideal choice for visible furniture joints and playground equipment. The integrated square neck prevents the bolt from spinning, allowing for easy, one-sided installation with a single wrench from the nut side.

Specifications:
- Thread Size: 3/8"-16 Coarse (UNC); Length: 3/4" (Measured from Under Head)
- Material: 304 (18-8) Stainless Steel; Full Thread

Pro-Tips:
1. Use a 3/8" drill bit to ensure a snug, structural fit for the square neck.
2. Pair with stainless steel flat washers and nuts on the nut side to distribute structural load and protect material surfaces.

Key Features

• Well-suited for Tight Spaces: The short 3/4 length is ideal for fastening thin materials or working in confined spaces where longer bolts would protrude and cause interference.
• Enhanced Security Drive: The smooth, rounded head lacks a drive socket, preventing unauthorized removal from the outside¡ªmaking it an excellent choice for gates, lockers, and outdoor fixtures.
• Heavy-Duty 3/8 Shank: Despite its short length, the 3/8 diameter provides superior shear strength and clamping force for demanding hardware and bracket installations.
• Marine-Grade 304 Stainless: Crafted from 18-8 (304) stainless steel, these bolts offer exceptional resistance to rust and corrosion in wet environments and with pressure-treated lumber.
• Instant Self-Locking: The precision square neck locks firmly into pre-drilled holes, allowing for a quick, one-handed installation without the need for a secondary wrench to hold the head.
