Prime-Line 9069290 Clothesline Hooks With Nuts

Prime-Line’s 9069290 set includes two hex nuts and is designed to install into a pre-drilled hole on a metal post. Size is 1/4 inch-20 by 4-1/4 inches. This option is best for metal posts in residential or light commercial setups where a straightforward, reliable hook bolt is needed. Best for quick, secure line attachment or temporary fixtures on metal posts. Limitation: designed for standard pre-drilled post installations; not ideal for heavy-duty outdoor hardware that requires longer or thicker bolts.
National Hardware N232-892 J Bolt 1/4″ x 4″

National Hardware offers a 1/4″ x 4″ J bolt with a steel wire construction and included hex nut. This is well-suited for general home and light industrial applications where durability and ease of installation matter. It’s a solid choice for anchoring fixtures to walls or posts with a clean, simple nut-and-bolt approach. Choose this if you want a straightforward, widely compatible fastener. Limitation: may not be ideal for high-load or corrosive environments without additional protective coating.
Alaisee 10 Pcs J Bolt Zinc-Plated

Alaisee provides a complete set: ten zinc-plated J-bolts (1/4″ x 4″), each with a matching nut and washer. This makes it ideal for concrete pad pouring, wood projects, outdoor installations, and general anchoring. Best for bulk projects or when you need readily available spare fasteners. Limitation: zinc plating offers basic corrosion resistance; consider environment and potential long-term exposure to moisture.
Prolinemax 4 Pc Marine Stainless J-Bolt

Prolinemax offers 1/4″ x 2.40″ J-Bolts in stainless steel T316, designed for marine or corrosive environments. Best for outdoor installations near water, docks, or salt-exposed settings where corrosion resistance is critical. A limitation is the shorter length compared to some outdoor mounting needs; ensure the bolt length accommodates your post thickness and washer/nut clearance.
QWORK M6 Hook Bolt 304 Stainless Steel Ring Screw

Note: This listing is included for reference, but the stated size is M6, not 1/4 inch. Best for users who need a corrosion-resistant hook bolt in metric sizing. Choose this if your project calls for M6 hardware; otherwise skip for 1/4″ threaded needs. Limitation: not compatible with 1/4″-20 systems without adapters.
QWORK Eye Bolt, 10 Pack 1/4″ 20 x 1″

QWORK’s eye bolts are made from high-quality 304 stainless steel, offering corrosion resistance and strong performance. The 1/4″-20 x 1″ size is suitable for rigging, anchoring, pulling, or lifting tasks. Best for temporary or semi-permanent setups requiring a reliable lifting point. Limitation: length is relatively short, which may limit certain high-load or deep installation needs.
Qlvily 4 Packs 316 Stainless Eye Bolts

Qlvily offers a 4-pack of 1/4″ UNC eye bolts made from 316 marine-grade stainless steel. Best for lifting and rigging where superior corrosion resistance is needed. These eyebolts have a lifting shoulder and smooth threads for easy installation. Limitation: 316 stainless is more expensive; consider cost against project needs and exposure to saltwater environments.
Buying Guide: How to Choose the Right 1/4 Hook Bolt
- Material matters: Choose stainless steel (304 or 316) for corrosion resistance, especially in outdoor or marine settings. Zinc-plated steel is fine for indoor or dry environments but may corrode over time.
- Thread and length: Ensure the thread type is 1/4″-20 or appropriate for your application. Match bolt length to post thickness, nut, and washer clearances to prevent crowding or failure.
- Head style and compatibility: Hook bolts, J-bolts, and eyebolts differ in installation and load paths. Select the style that aligns with your anchoring or lifting needs.
- Inclusion of nuts and washers: Some sets include nuts and washers; consider whether you need to purchase these separately for your project.
- Environment and load: For heavy-duty or outdoor marine projects, prioritize stainless steel with high corrosion resistance and sufficient length to accommodate mounting hardware.
- Bulk vs. single-use: If undertaking multiple installations, bulk packs (like 10 or 4- packs) offer cost efficiency and ready spares.
